May 24, 2018 · I want to create a program that prompts for input and based on this input provides with a tailored reply. As the code is, it works perfectly, with the exception that it is not looping at all. (After running the script in CMD or Powershell it terminates and dies.)

Apr 24, 2025 · When it comes to user input, these loops can be used to prompt the user for input and process the input based on certain conditions. In this article, we will explore how to use for and while loops for user input in Python.

Aug 18, 2023 · In this Byte, we will explore how to use for and while loops for user input in Python. User Input with For Loops. The for loop in Python is used to iterate over a sequence (such as a list, tuple, dictionary, string, or range) or other iterable objects. Iterating over a sequence is called traversal. Let's see how we can use a for loop to get ...

Mar 11, 2025 · Learn how to get user input in Python while loops effectively. This guide covers using the input() function to gather data until a condition is met, implementing input validation, and creating menu-driven programs.

Dec 7, 2021 · Example while loop user input in Python. A simple example code takes input from the user and adds values into a list until a quit is entered by the user.

while loops are useful when the number of iterations is unknown, such as waiting for a condition to change or continuously processing user input. while True in Python creates an infinite loop that continues until a break statement or external interruption occurs.

Nov 13, 2020 · User Input Using a While Loop Now let's see an example of a while loop in a program that takes user input. We will the input() function to ask the user to enter an integer and that integer will only be appended to list if it's even.

There are two ways to do this. First is like this: inp = raw_input() # Get the input. if inp == "": # If it is a blank line... break # ...break the loop. The second is like this: inp = raw_input() # Get the input again. Note that if you are on Python 3.x, you will need to replace raw_input with input.

How to ask the user for input until they give a valid response in Python. Here's one clean way: #more. use a while True loop; use input() to get the user input; use a try-except block to catch invalid inputs; use an else block to break if the input is valid

Apr 28, 2025 · While loop is used to execute a block of code repeatedly until a given boolean condition evaluates to False. If we write while True, the loop will run indefinitely unless a break statement is used to exit it. Let’s look at different examples of the while loop to better understand how it can be used in different situations.
