Avoid using input() in Python 2.x. It evaluates arbitrary expressions
that can be a security risk at worst, but at least a source of bugs.
Instead use raw_input(). This returns an unevaluated string. You can
convert it to a number with int():
>>> grams = int(raw_input("How many grams? "))
How many grams? 28
>>> grams
28
Also, "print" is a statement in 2.x; you don't call() it as a
function, not unless you import the print() function from __future__:
>>> print # print an empty line
>>> from __future__ import print_function
>>> print # now it's a function
<built-in function print>
Finally, you don't have to terminate any lines with a semicolon.
Python's grammar allows it, but it's not idiomatic style.
