You should use indentatation to make your code more readable and therefore easier to understand.

What your code does is print user_i lines that consist of user_i-tall+1 spaces and then tall+1 hashes.

Subsequently you have 'growing' rows of hashes that form a pyramid.
What you are doing is equivalent to this pseudo code:

    print " " (user_i-i+1) times
    print "#" (i+1) times
