How to Ask Again in Python: A Guide to Repeating User Input

Are you tired of writing code that only runs once? Do you want to create a Python program that can repeat user input until a certain condition is met? Then you need to learn how to ask again in Python.

Asking for user input is a common task in programming, but what happens when you need to repeat that input multiple times? In this guide, we’ll walk you through the process of asking again in Python, from the basics of input function to creating loops that can repeat user input over and over again.

Getting Started with User Input

Before we can repeat user input, we need to understand how to get user input in the first place. In Python, we use the input() function to get user input.

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

This code prompts the user with the question “What is your name?” and stores their response in the variable name. Now, let’s take a look at how we can continuously ask for input using a loop.

Using a While Loop to Repeat User Input

The while loop is a fundamental programming concept that allows you to repeat a block of code while a certain condition is true. We can use a while loop to repeatedly ask for user input until we get the answer we’re looking for.

answer = ""

while answer != "yes":
    answer = input("Do you want to continue? ")

This code prompts the user with the question “Do you want to continue?” and continues to ask until the user responds with “yes”. Note that the variable answer is initialized as an empty string so that the loop will run at least once.

Adding Error Handling to User Input

When asking for user input, it’s important to include error handling to prevent the program from crashing if the user enters invalid input. One way to do this is to use a try/except block.

while True:
        age = int(input("What is your age? "))
    except ValueError:
        print("Please enter a valid integer.")

This code asks the user for their age, but if they enter a non-integer value, the program will print an error message and ask again. The while True loop ensures that the user will be prompted until they enter a valid integer.

Repeating User Input with a For Loop

In addition to using a while loop, we can also use a for loop to repeat user input a specific number of times.

for i in range(3):
    email = input("Enter your email address: ")

This code prompts the user for their email address three times using a for loop. Note that the variable i is not used in the loop body, since we only care about repeating the input.

Using Functions to Repeat User Input

Functions are a powerful tool in Python, and can be used to repeat user input in a more modular way.

def get_name():
    name = input("What is your name? ")
    return name

for i in range(3):
    name = get_name()

This code defines a function get_name() that asks the user for their name and returns the input. We can then use this function to prompt the user for their name three times using a for loop.


Asking again in Python can be a useful technique for creating programs that can handle user input in a flexible way. By using loops and error handling, we can create programs that can repeat user input until a certain condition is met. Whether you’re creating a game, a chatbot, or a data collection tool, the ability to ask again in Python is an essential skill for any programmer. So go ahead and try it out for yourself!
