Python Programming - Variables - Discussion

In Python, a global variable is a variable that is defined outside of any function and can be accessed from anywhere in the code. A local variable, on the other hand, is a variable that is defined within a function and can only be accessed within that function.

Global variables exist throughout the entire program's execution, while local variables are created when a function is called and are destroyed when the function completes. Therefore, global variables have a longer lifespan than local variables.
