If you mean `fromfunction()` then you don't give the name of the function
as string but the function itself as argument.  And what you call
attributes are arguments.

Functions are objects in Python, you can pass them around like any other
object/value.

In [18]: def f(func, arg):
   ....:     return func(arg)
   ....:

In [19]: f(int, '42')
Out[19]: 42

In [20]: f(str.split, 'a b c')
Out[20]: ['a', 'b', 'c']
