8 Best place to Learn Python Absolutely free - Course Joiner

1. Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects. Python is dynamically typed and garbage-collected. It supports multiple programming paradigms, including procedural, object-or
2. Python is a high-productivity dynamic programming language that is widely used in science, engineering, and data analytics applications. There are a number of factors influencing the popularity of python, including its clean and expressive syntax and standard data structures, comprehensive batteries included standard library, excellent documentation, broad ecosystem of libraries and tools, availability of professional support, and large and open community. Perhaps most important, though, is the high productivity that a dynamically typed, interpreted language like Python enables. Python is nimble and flexible, making it a great language for quick prototyping, but also for building complete systems.
3. Python is one of the most widely used general-purpose programming language used in several companies. It has a wide range of applications ranging from Web development, scientific and mathematical computing to desktop graphical user Interfaces. However, it is primarily used in the back-end programming. It also plays a very crucial role in software testing, control and management. Python is also incredibly useful at integration of tasks. Websites like YouTube, Quora, Flipkart, Slack, Uber, Clou
4. 1. Basic syntax requires you to know less language constructions - e.g. no program in C# can be written w/o declaring a class; you need to know what’s compilation, assemblies, namespaces, classes, methods, public/private/static keywords, etc. On the other hand, you can write a program even without declaring a function in Python. So it’s easier to learn Python iteratively: you need to know almost nothing at start, and use more and more features while studying it deeper. In contrast, C# requir
5. 1. Take advantage of Python’s clean syntax to build games quickly 2. Discover distinct frameworks for developing graphical applications 3. Implement non-player characters (NPCs) with autonomous and seemingly intelligent behaviors 4. Design and code some popular games like Pong and tower defense 5. Compose maps and levels for your sprite-based games in an easy manner 6. Modularize and apply object-oriented principles during the design of your games 7. Exploit libraries like Chimpunk2D, cocos2
6. 1. Launch GPU code directly from Python 2. Write effective and efficient GPU kernels and device functions 3. Use libraries such as cuFFT, cuBLAS, and cuSolver 4. Debug and profile your code with Nsight and Visual Profiler 5. Apply GPU programming to datascience problems 6. Build a GPU-based deep neuralnetwork from scratch 7. Explore advanced GPU hardware features, such as warp shuffling
7. Functions are declared with the def keyword. Optional arguments areset in the function declaration after the mandatory arguments by being assigneda default value. For named arguments, the name of the argument is assigneda value. Functions can return a tuple (and using tuple unpacking you caneffectively return multiple values). Lambda functions are ad hocfunctions that are comprised of a single statement. Parameters are passed byreference, but immutable types (tuples, ints, strings, etc) canno
8. Code is typically organized into functions. A function encapsulates part of your code. Functions allow you to reuse bits of functionality without copy-pasting the code. Here is a function that tells whether an integer number is even or not:There are several things to note here: 1. A function is defined with the def keyword. 2. After def comes the function name. A general convention in Python is to only use lowercase characters, and separate words with an underscore _. A function name generall
9. Functions are reusable blocks of code that perform specific tasks. For example, you could write a function to add two numbers together, or print out a string.You define and call a function as shown in the example below:Can you guess what the output of this program is before you run it? Check your answer below:[spoiler]It will print out \"Hi\" three times, because the for loop will call the function hello three times.[/spoiler]The indented code defines the statements which run when you call the
10. In Python, you define a function via the keyword def followed by the function name, the parameter list, the doc-string and the function body. Inside the function body, you can use a return statement to return a value to the caller. There is no need for type declaration like C/C++/Java.The syntax is:Take note that you need to define the function before using it, because Python is interpretative.This example elaborates on the function's doc-string: 1. The first line \"(number) -> (number)\" speci
11. Python is a dynamic, interpreted (bytecode-compiled) language. There are no type declarations of variables, parameters, functions, or methods in source code. This makes the code short and flexible, and you lose the compile-time type checking of the source code. Python tracks the types of all values at runtime and flags code that does not make sense as it runs.An excellent way to see how Python code works is to run the Python interpreter and type code right into it. If you ever have a question
12. Python is an interpreted, object oriented high-level scripting language used for general-purpose programming. It was created by Guido van Rossum and first released in 1991. Python source code is also available under the GNU General Public License (GPL). JavaTpoint offers Python tutorials and examples to help you learn Python programming from scratch.Python interpreters are available for many operating systems and its program is processed at runtime by the interpreter which means you do not ne
13. Python, the high-level, interactive object oriented language, includes an extensive class library with lots of goodies for network programming, system administration, sounds and graphics. Debian always provides at least two versions of Python, the latest stable Python 2 release, and the latest stable Python 3 release. It may also provide additional versions, as well as tons of third party packages. Python is an important part of the Debian ecosystem. Python is very easy to learn. You can begi
14. Program make_python_prog.py is a code generator that produces Python programs that parse command line arguments using Python 2.7's 'argparse' module.The purpose of the program is to save typing. It is not a goal to handle all features of the 'argparse' module, but rather to produce code that runs, and, if desired, can be easily modified to take advantage of more advanced argparse features; and of course to modify the program to do whatever the programs is intended to do.It is a goal to make t
15. Python 3 is the latest version of the language, and is incompatible with Python 2. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. Also, the standard library has been reorganized in a few prominent places. For an overview of the differences, visit Python2orPython3 and the relevant chapter in Dive into Python 3.To install the latest versi
16. Since Python is so integral to Gentoo there is little chance it is not installed. Doing so would be like removing the heart from Gentoo. There is occasion where Python must be recompiled in order to add new features or to upgrade.
17. Python for .NET is available as a source release and as a Windows installer for various versions of Python and the common language runtime from the Python for .NET website . On Windows platforms, you can choose to install .NET-awareness into an existing Python installation as well as install Python for .NET as a standalone package. The source release is a self-contained \"private\" assembly. Just unzip the package wherever you want it, cd to that directory and run python.exe to start using it.
18. Install a working copy of Python 2.7, 3.5, or 3.6, including the numpy library. The simplest method is to install one of the pre-configured installations such as Anaconda, which contains everything you need for the IDL-Python bridge.It is recommended that you install Python in a directory with a name that does not include spaces or special characters.To verify your Python installation, use the following Python commands:where x.x.x are the respective Python and Anaconda versions.The next step
19. One unusual Python feature is that the whitespace indentation of a piece of code affects its meaning. A logical block of statements such as the ones that make up a function should all have the same indentation, set in from the indentation of their parent function or \"if\" or whatever. If one of the lines in a group has a different indentation, it is flagged as a syntax error.Python's use of whitespace feels a little strange at first, but it's logical and I found I got used to it very quickly.
20. There is one more important situation in which whitespace is significant in Python code. Indentation—whitespace that appears to the left of the first token on a line—has very special meaning.In most interpreted languages, leading whitespace before statements is ignored. For example, consider this Windows Command Prompt session:In the second statement, four space characters are inserted to the left of the echo command. But the result is the same. The interpreter ignores the leading whitespace
21. Indentation refers to the spaces that may appear at the beginning of some lines of code. This is a particular aspect of Python’s syntax.In most programming languages, indentation is optional and is generally used to make the code visually clearer. But in Python, indentation also has a syntactic meaning. Particular indentation rules need to be followed for Python code to be correct.In general, there are two ways to indent some text: by inserting a tab character (also referred to as t), or by i
22. Unlike many other computer languages, like C++ and java, Python uses indentation to determine blocks of code. The following pseudocode below will help demonstrate.As we can see, there can be multiple blocks of code. You can also contain blocks of code within another block of code, so long as it indents. There isn't a limit on the indent, but it must be kept constant or you'll get an error.Although you're allowed to use white spaces and tabs, it's preferred that you use white spaces. Also, you
23. Python is a multi-paradigm language; it notably supports imperative, object-oriented, and functional programming models. Python functions are objects and can be handled like other objects. In particular, they can be passed as arguments to other functions (also called higher-order functions). This is the essence of functional programming.Decorators provide a convenient syntax construct to define higher-order functions. Here is an example using the is_even() function from the previous Functions
24. Yay, it's time to program! The next few sections will talk about some very basic programming. We will program a few programs as a demonstration.
25. PEP-8 has also some programming recommendations. I listed some here, check the link for more. 1. Do not compare boolean values to True or False using the equivalence operator:fever = get_temperature() >= 38# Not recommendedif fever == True: print('You are ill!')# Recommendedif fever: print('You are ill!') 2. Use the fact that empty sequences are falsy in if statements:my_list = []# Not recommendedif not len(my_list): print('List is empty!')# Recommendedif not my_list: print('List is empty!')
26. As mentioned above, another strength of Python is the availability of a functional programming style. As may be expected, this makes working with lists and other collections much more straightforward.
27. Python list is an array like construct which stores arbitrarily typed objects in an ordered sequence. It is very flexible and does not have a fixed size. Index in a list begins with zero in Python. 1. It is a heterogeneous collection of items of varied data types. For example, a list object can store the files in a folder, or the employee data in a company etc.
28. Beside strings and integers, Python has all sorts of different types of objects. Now we're going to introduce one called list. Lists are exactly what you think they are: objects which are lists of other objects. :)Go ahead and create a list:command-lineYes, this list is empty. Not very useful, right? Let's create a list of lottery numbers. We don't want to repeat ourselves all the time, so we will put it in a variable, too:command-lineAll right, we have a list! What can we do with it? Let's s
29. A list contains a sequence of items. You can concisely instruct Python to perform repeated actions on the elements of a list. Let’s first create a list of numbers as follows:Note the syntax we used to create the list: square brackets [], and commas , to separate the items.The built-in function len() returns the number of elements in a list:Now, let’s compute the sum of all elements in the list. Python provides a built-in function for this:We can also access individual elements in the list, us
30. Creating a list.Counting elements:Getting a element. Use the syntax list[index]. Index start at 0. Negative index counts from right. Last element has index -1.Extracting a sequence of elements (aka sublist, slice): list[start_index:end_index].WARNING: The extraction is not inclusive. For example, mylist[2:4] returns only 2 elements, not 3.Modify element: list[index] = new_valueA slice (continuous sequence) of elements can be changed by assigning to a list directly. The length of the slice nee
31. The not operator negates the value of the expression. In other words, if the expression is True, then the not operator returns False and if it is False, it returns True. Unlike the other two logical operators, the not operator is a unary. The precedence of the not operator is higher than that of and and or operator. Its syntax is:Syntax: not operandThe truth table for not operator is as follows:Here are some examples:
32. Python includes the +, -, *, /, % (modulus), and ** (exponentiation) operators, with their usual mathematical precedence.Traditionally, x / y performed integer division if both x and y were integers (returning the floor of the quotient), and returned a float if either was a float. However, because Python is a dynamically-typed language, it was not always possible to tell which operation was being performed, which often led to subtle bugs. For example, withA call to mean([3.0, 4.0]) would retu
33. Logical operators are used to compare two conditional statements. Following are the logical operators that we have in python.
34. Okay, so let's see a slightly bigger example that we can actually run. The following code is a pretty simple asynchronous program that fetches JSON from Reddit, parses the JSON, and prints out the top posts of the day from /r/python, /r/programming, and /r/compsci.The first method shown, get_json(), is called by get_reddit_top() and just creates an HTTP GET request to the appropriate Reddit URL. When this is called with await, the event loop can then continue on and service other coroutines w
35. The following code example demonstrates this with a simple Mandelbrot set kernel. Notice the mandel_kernel function uses the cuda.threadIdx, cuda.blockIdx, cuda.blockDim, and cuda.gridDim structures provided by Numba to compute the global X and Y pixel indices for the current thread. As in other CUDA languages, we launch the kernel by inserting an execution configuration (CUDA-speak for the number of threads and blocks of threads to use to run the kernel) in brackets, between the function name and the argument list: mandel_kernel[griddim, blockdim](-2.0, 1.0, -1.0, 1.0, d_image, 20). You can also see the use of the to_host and to_device API functions to copy data to and from the GPU.
36. This section is for experienced programmers to look at Python's syntaxes and those who need to refresh their memory. For novices, go to the next section.
37. Use Python commands in the following ways to convert a 10 x 2 matrix representing Cartesian coordinates to Polar coordinates.
