Python: Global and Local Variables

Global Variables:

Global variables are the one that is defined and declared outside a function and we need to use them inside a function. This means that a global variable can be accessed inside or outside of the function.

Example:

a = "Hello World!!"

def func_1():
    print(a)

func_1() 

Output: Hello World!!

Local Variables:

Local variables are declared inside the function's body or in the local scope is known as a local variable.

Example:

def func_1():
    a = "Hello!!"
    print(a)

func_1()
