>>> import math
>>> dir(math)
['__doc__', '__file__', '__name__', 'acos', 'asin', 'atan', 'atan2', 
'ceil', 'cos', 'cosh', 'degrees', 'e', 'exp', 'fabs', 'floor', 'fmod', 
'frexp', 'hypot', 'ldexp', 'log', 'log10', 'modf', 'pi', 'pow', 
'radians', 'sin', 'sinh', 'sqrt', 'tan', 'tanh']


Note that dir() gives you a list of "interesting" names. You can also use 
math.__dict__.keys() or the inspect module.

Once you have a key, you can get the actual object you want with getattr:

>>> key = 'acos'
>>> getattr(math, key)
<built-in function acos>
