Socket programming is a technique for connecting two applications, or nodes, on a network by using sockets as endpoints for transferring and receiving data. It is a key networking concept that allows programs to communicate data over local and remote networks. In Python, the socket module contains...
In this tutorial, you'll explore Python's __pycache__ folder. You'll learn about when and why the interpreter creates these folders, and you'll customize their default behavior. Finally, you'll take a look under the hood of the cached .pyc files.
Let’s see the steps to how to set up a test environment to perform Hypothesis testing in Python. Create a separate virtual environment for this project using the built-in venv module of Python using the command. Activate the newly created virtual environment using the activate script present...

The Walrus operator (:=) was introduced in Python 3.8, it can be useful in situations where you'd want to assign values to variables within an expression.def some_func(): # Assume some expensive computation here # time.sleep(1000) return 5 # So instead of, if some_func(): print(...
A notable limitation of the Python 3.5 implementation is that it was not possible to use await and yield in the same function body. In Python 3.6 this restriction has been lifted, making it possible to define asynchronous generators: async def ticker(delay, to): """Yield numbers from 0 to...
If the__name__ == "__main__"expression isFalse, then Python skips the indented code. But when is__name__equal to the string"__main__"? In the previous section, you learned that this is the case when you run your Python file as a script from the command line. While that covers...

Python 2.7 is planned to be the last of the 2.x releases, so we worked on making it a good release for the long term. To help with porting to Python 3, several new features from the Python 3.x series have been included in 2.7....
In Python 3.8, the following code would generate a syntax error. print ("Hello" print ("What's going on?") File ".test.py", line 2 print ("What's going on?") ^ SyntaxError: invalid syntax Not very helpful, because the real problem is one line earlier. Python 3.10 generates a ...
