>>> import math
>>> dir(math)
['__doc__', '__file__', '__name__', 'acos', 'asin', ... ]
>>> 
>>> math.__dict__['acos'](0)
1.5707963267948966
>>> getattr(math, 'asin')(0)
0.0

Instead of storing the names of the functions, better to store the
functions themselves:

>>> my_list = [math.acos, math.asin]
>>> my_list[0](1)
0.0


Hope this helps,
