Global function Python

Python Global function can define using the def keyword followed by the name of the function and the parameters it takes (if any). A global function in Python is a function that can be accessed from anywhere in a program, without the need to import it or specify its location within the code.

def my_function():
    print("Hello, world!")

Global function Python example

A simple example code set_value is a global function that sets the value of my_var, which is a global variable. get_value is another global function that returns the value of my_var. Both functions can be called from anywhere in the program.

def set_value(val):
    global my_var
    my_var = val


def get_value():
    return my_var


set_value(100)
print(get_value())
