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.

Mar 24, 2012 · You need a loop: while True: choice = raw_input("What would you like to do") if choice == '1': print("You chose 1") elif choice == '2': print("You chose 2") elif choice == '3': print("You chose 3") else: print("That is not a valid input.")

To take user input in a while loop: Use a while loop to iterate until a condition is met. Use the input() function to take user input. If the condition is met, break out of the while loop.

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.

Aug 18, 2023 · In this Byte, we will explore how to use for and while loops for user input in Python. 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 user input.

May 8, 2022 · Once Python receives the user’s input, it assigns that input to a variable to make it convenient for you to work with. For example, the following program asks the user to enter some text, then displays that message back to the user:

Mar 11, 2025 · When programming in Python, user input is a critical aspect that enhances interactivity. One effective way to continuously gather input until a specific condition is met is by using a while loop. This method allows developers to create dynamic applications that respond to user needs in real-time.

Dec 7, 2021 · Just need to take input from the user and evaluate those values in the while loop expression condition. A simple example code takes input from the user and adds values into a list until a quit is entered by the user. # Start a loop that will run until the user enters 'quit'. new_name = input("Enter Name, or 'quit': ") if new_name != 'quit':

Nov 3, 2016 · All you need to do is to convert it. sums = sums + float(input("Pleas input number " + str(w+1) + " ")); If you want to make it even better, you can use try/except to deal with invalid inputs. Also, import sys is not needed and you should avoid using semicolon. try: sums = sums + float(input("Pleas input number " + str(w+1) + " "))

Feb 21, 2025 · Using a for loop to take list input is a simple and common method. It allows users to enter multiple values one by one, storing them in a list. This approach is flexible and works well when the number of inputs is known in advance. Let’s start with a basic way to input a list using a for loop in Python. Output:
