Don't feel too badly about it. Even very experienced programmers get
bitten by this issue. Until someone points it out, it's certainly not
obvious.

Floating points variables ...

Try replacing with: print "%0.20f" % t
The thing you're missing is that floating point arithmetic isn't (in
general) exact - but when it's printed it's rounded.

This seems strange to me, but perhaps I am just missing something:
In [12]: t = 0.
In [13]: time = 10.
In [14]: while t < time:
: print t
: t += 1.

0.0
1.0
