Others have already answered that question. This posting is a
pre-emptive strike to head off the next half-a-dozen questions.

Some of us are interested in the process by which great pieces of code
arise, how they are meticulously honed and polished, which craftpersons
contributed what ... is it possible for you to publish the earlier versions?

"number" will refer to one of: 0, 1, ......, 98, 99

so you'll get a strange result by using zero here; try -1 instead

"guess" will refer to a string e.g. "42" which will *not* compare equal
to the integer 42. Also you should use raw_input, not input.
so do this:
guess = int(raw_input("Guess a number: "))

This will cause your program to ask TWICE per trip around the loop. Lose it.

... and again.

General advice:
1. Look on the Python web site (http://www.python.org) for an
introduction to Python for non-programmers.
2. Join the Python tutor list.
3. In this news group, read a little more than the threads that you have
started; this guessing game was discussed in a thread started by
somebody calling themselves ChuckDubya on 29 June!! Homework??
HTH,
John
