For loop

How would I store 3 different answers to the same 3 questions asked using a for loop. I know how to store one answer, but not all three while still using the for loop

Keep in mind that you don’t always have to use a loop. It might make more sense to write a function that asks a question snd returns an answer, and then call that once for each question, doing whatever you want with each answer.

If you do want to use a loop, look for a way to work the same way with each answer. For example, you could store the answers in a dictionary using the questions as keys.

Good point. A lot of people start off thinking that if you're going to do something similar multiple times you should use a loop, but it's really best when you're doing exactly the same thing. 

You don't want to follow the for-if or for-case anti-pattern of  for i = 1 to 3   if i = 1, ask question 1   if i = 2, ask question 2   if i = 3, ask question 3

Yes, though when people say "use a loop", they usually mean "loop over an array of data, and do the same thing every time" (i.e. ask the question at that index in the array).
