Can string be callable as a method ?

[Jia Lu]

Hi all
I tried to scan a directory and __import__ all modules ,
<log>
imported module: help
imported module: __init__
imported module: hi
imported module: thanks

and I scaned all methods in them, and put them to a list like:

[['f_chelp', 'f_help'], [], ['f_exclaim', 'f_hi', 'random'],
['f_thanks', 'random']]

But how can I call them from that list??

Thank you.

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,
