WHAT IS THE GLOBAL VARIABLE IN PYTHON?

Global Variables in python are the Variables that are created outside of a function. Global variables can be used anywhere by everyone within the program.

To create a global variable inside a function, you can use the “global” keyword and its scope will be global.

Example-

x=”globalVariable1″   #variable declaration

y=”globalVariable2″   #variable declaration

def myfunction():     #user function defined

y=”privateVariable” #private variable available within myfunction()

global z            #keyword global defines global variable in function

z=”globalVariable3″ #assigning value to variable

print(x)            #access global variable x

print(y)             #access private variable y instead of global variable y

print(z)             #access to variable declared as global in the function

myfunction()      #call to myfunction()

print(x)              #access global variable x

print(y)            #access global variable y

print(z)           #acces of variable outside the function
