The variables that are declared outside the scope of a function are defined as global variables in python. As a result, a user can access a global variable inside or outside the function.
What is a global variable in python? What is __ Getattr __ in Python and what it is used for? How do you range a number in Python? How do you comment out a paragraph in Python? What is __ del __ in Python? What is the function of == in Python? Is it OK to use global ...
1. Global scope¶Any variable defined outside a non-nested function is called a global. As the name suggests, global variables can be accessed anywhere.Example:¶side = 5 # defined in global scope def area(): return side * side def circumference(): return 4 * side print(f"Area of...
A simple swap function in Python is generally considered a function that takes two initialized variables,a = val_aandb = val_b, and returns a result ofa = val_bandb = val_a. The function accepts variables of arbitrary types, or more precisely, variables that are assigned with objects of ...
Python's Global Interpreter Lock or GIL, in simple words, is a mutex (or a lock) that allows only one thread to hold the control of the Python interpreter at any one time. In this article you'll learn how the GIL affects the performance of your Python pr
Functional programming is a paradigm where the program is mainly an evaluation of (mathematical) functions, and is not through a series of defined steps that change the state of the program. Purely functional programs avoid the change of state (side effects) and mutable data. In Python, ...
