Task 3: Global vs. Local variables Python (SHOW SCREEN SHOTS OF THE INPUT AND OUTPUT )

Variables that are defined inside a function body have a local scope, and those defined outside have a global scope. This means that local variables can be accessed only inside the function in which they are declared, whereas global variables can be accessed throughout the program body by all functions. When you call a function, the variables declared inside it are brought into scope.

#!/usr/bin/python

3

total=0# This is global variable. #

Function definition is here def sum(

arg1, arg2 ): # Add both the parameters

and return them." total= arg1 + arg2;#

Here total is local variable. print("Inside

the function local total : ", total) return

total

# Now you can call sum function

sum(10,20) print("Outside the function

global total : ", total )
