automatically set vars' names python

Question

I'm working on python program and i want something like this:

for i in range(1,n+1):
    var(a+str(i)) = input()
    #do something

So that variables are a1,a2,a3,etc. Can this be done, and how?

Why do you want that? Use a dict instead! And why was this question upvoted? For what reason? — user2665694

You should get acquainted with the idea of zero-based numbering. The need to go through contortions like range(1,n+1) instead of range(n) should alert you to the fact that you're doing something wrong. — Tim Pietzcker

I need 'i' on multiple places, so I'd have to put (i+1) everywhere else. So range(1,n+1) makes the code shorter in this case... — Mirac7

You don't want to do that, trust me. You want to use a dictionary

vars = {}
for i in range(1,n+1):
    vars[i] = input()
    #do something

or, since all the numbers are sequential in your special case, a list:

vars = [None]  #  initialize vars[0] with None
for i in range(n):
    vars.append(input())
    #do something

Now you can access your variables like vars[2], vars[5] etc.

(Of course, vars is a terrible name for a variable - you should use a meaningful name instead. This is just meant as an example.)
