Hey John,

Please reply to the list, rather than to people directly.  Clicking "reply to
all" is probably what you want.

Nah, it's much, much simpler than that.

time.time just returns a floating point number.  How do you convert a number
into a string?

Programming languages differentiate between numbers and strings.  32 is a
number; you can do computations with it (add, multply, etc).  "32" is a string;
this means it is the character "3" followed by the character "2".  Python (and
most other programming languages) treats them very differently.


>>> x = 32
>>> x + 1
>>> x * 3 / 4
>>> s = "32"
>>> s + "1"
>>> s + "foo"

You have to decide what you need.  Your program compars numbers with the answer
(your random number).  In order to do this comparison, you need to have your
answer as a number, not as a string.

Hope this helps.
