How to string format in python?

Question

I have a new python learner, I want to ask a question about string format.

a = 3
len = 5

I want to format a as a binary number and the number length is 5. So I want to format it to '00011'.

How can I do in python?

Isn't it sort of counter-productive to ask if an answer is the best one *when attempting to answer another question*? – Andrew Li Aug 23 '16 at 02:50
@zondo I'm sorry. As a new user in stack overflow, I have made some mistakes. – Chauncey Aug 23 '16 at 06:09
