Input and Output in Python

The print() function is used for output in various formats and the input() function enables interaction with users.

Taking Input using input()

Python's input() function is used to take user input. By default, it returns the user input in form of a string. 

Output

Enter your name: GeeksforGeeks
Hello, GeeksforGeeks ! Welcome!

The code prompts the user to input their name, stores it in the variable "name" and then prints a greeting message addressing the user by their entered name.

Printing Output using print()

print() function allows us to display text, variables and expressions on the console. In the below example, "Hello, World!" is a string literal enclosed within double quotes. When executed, this statement will output the text to the console.

Hello, World!

Printing Variables

We can use the print() function to print single and multiple variables. We can print multiple variables by separating them with commas.

We can also take multiple inputs at once from the user in a single line, splitting the values entered by the user into separate variables for each value using the split() method:

Output

Enter two numbers: 10 20
10 20

Taking Different types of User Input

We can change the user input from default string type to any other type (int, float, etc) by typecasting.

Output

How old are you?: 23
Evaluate 7/2: 3.5
23 3.5
