A typical example of this practice is when you have a module that defines a variable to hold some configuration parameters. You can import this variable into your global scope and use it as you’d use any other global variable. As a quick example, say that you have the following config....
A side effect can be, for example, printing something to the screen, modifying a global variable, updating the state of an object, writing some text to a file, and so on.Modifying global variables is generally considered a bad programming practice. Just like programs with complex expressions,...
# Local variable x inside the function x = 5 print("Value of x inside the function:", x) # Calling the function # Global variable x x = 10 func() print("Value of x outside the function:", x) Output: Explanation: Here, the function func() has a local x = 5, which exists on...
6. Python virtual environment best practices To ensure order and consistency across your data projects, creating a virtual environment for every project you start is a good practice. Virtual environments, also known as virtualenvs, help decouple and isolate versions of Python and the libraries re...
What Is the Python Global Interpreter Lock (GIL)? In this quiz, you'll test your understanding of the Python Global Interpreter Lock (GIL). The GIL behaves like a mutex that allows only one thread to hold the control of the Python interpreter. This has advantages, but can be a performanc...
defmy_function():x=5# local variableprint(x)# prints 5my_function()print(x)# prints 10 In this example, the local variable x within the function takes precedence over the global variable x. When my_function is called, it prints the value of the local variable x (i.e., 5). However...

As, modules help avoid clashes between global variable names, in a similar manner, packages help avoid clashes between module names.Creating a package is easy since it makes use of the system's inherent file structure. So just stuff the modules into a folder and there you have it, the ...
