Getting Input from the User
The built-in input function requests and obtains user input, that is, it tells the user what
to type and waits for the user to respond.

name = input("What's your name? ")
What's your name? John
print(name)
John

name = input("What's your name? ")
What's your name? 'John'

print(name)
'John'

Function input Always Returns a String

value1 = input('Enter first number: ')
Enter first number: 10
value2 = input('Enter second number: ')
Enter second number: 20
print(value1 + value2)
'1020'

Getting an Integer from the User

value1 = int(input('Enter first number: '))
Enter first number: 10
value2 = int(input('Enter second number: '))
Enter second number: 20
print(value1 + value2)
30
