For example, if we want to ask a user for a number between 1 and 10, we don't know how many times the user may enter a larger number, so we keep asking "while the number is not between 1 and 10". A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).. Here are two code examples to demonstrate how to loop through a range.
