HI all, started to learn python for a uni course im doing, im already a seasoned programmer, i find python in comparision to be.. well, annoying and crappy

Anyhow, im waiting for a few books I ordered to arrive, until then, im trying to use the math sqrt function on a float value, on running the program i get the error:

Traceback (innermost last):
File "sqrt.py", line 22, in ?
print sqrt(number)
NameError: sqrt

Now, do I have to somehow install a math module? If so how? Cheers,
Taz

Yes... you need to import the math module (RTFM).

>>> import math
>>> print math.sqrt(5)
2.2360679775
>>>

or you can do:

>>> from math import *
>>> print sqrt(5)
2.2360679775
>>>



Python isn't annoying and crappy
It's just that you're not used to it.
I would suggest a few good tutorials:
