Answer 1

Write a python program that takes two numbers  and prints their sum 

Getting User Input in Python

• input ( prompt )
• raw_input ( prompt )

The input() or  raw_input() function allows user input. These functions have an optional parameter, commonly known as prompt, which is a string that will be printed on the screen whenever the function is called.

In Python 3, raw_input() function has been deprecated and replaced by the input() function.

The user-entered value is always converted to a string and then assigned to the variable.

example-

a=input("enter a value")

print(type(a)) 

#output type of a is string by default in python

a=int(a)

#convert from string to integer by using inbuilt int()

print(type(a)) #output type of a is integer

Output- <class 'str'> 

<class 'int'>

Program :

a=int(input("enter first number : "))

b=int(input("enter second number : "))

print("sum of",a, "and",b,"is",a+b)

Output : 

enter first number :  4

enter second number : 6

sum of 4 and 6 is 10
