Feb 19, 2024 · 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.

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) + " "))

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.

Dec 5, 2024 · In this article, we will see how to take a list as input from the user using Python. The input() function can be combined with split() to accept multiple elements in a single line and store them in a list. The split() method separates input based on spaces and returns a list. Output:

Apr 9, 2024 · To use a for loop to take user input: Declare a new variable and initialize it to an empty list. Use the range() class to loop N times in a for loop. On each iteration, append the input value to the list. my_list.append(input('Enter a country: ')) print(my_list) The first example takes multiple string inputs from a user and appends them to a list.

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.

Python For Loops. A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in …
