Taking Input in Python

Prompting the User for Input

Adding a prompt message makes it clear what the user is expected to enter.

• Python

Python

name = input("What is your name? ")

print("Nice to meet you, " + name + "!")

Run Code

Output

What is your name? Bob
Nice to meet you, Bob!

Type Conversion for User Input

When taking input, it's often necessary to convert the input from a string to another data type.

Converting String to Integer

number = int(input("Enter a number: "))
print("You entered the number " + str(number))

Converting String to Float

decimal_number = float(input("Enter a decimal number: "))
print("You entered the number " + str(decimal_number))

Example of Type Conversion

• Python

Python

num1 = int(input("Enter the first number: "))

num2 = int(input("Enter the second number: "))

sum = num1 + num2

print("The sum of the two numbers is " + str(sum))

You can also try this code with Online Python Compiler

Run Code

Output

Enter the first number: 10
Enter the second number: 20
The sum of the two numbers is 30

Frequently Asked Questions
