I have a list of the names of imported functions, which I can call as follows:
from myfile import function1
from myfile import function2
function1()
function2()
How would I call the functions from a list of names? For example:
fns = ['function1', 'function2']
for fn in fns:
fn()
How would I do the above properly?
don't use a list of strings, just store the functions in the list:
fns = [function1, function2]
for fn in fns:
fn()
You can access to function objects from globals() namespace, but note that this is not a general approach, since first of all your imported objects should be callable (have __call__ attribute) and they should be present in global name space.:
for fn in fns:
try:
globals()[fn]()
except KeyError:
raise Exception("The name {} is not in global namespace".format(fn))
Example:
>>> from itertools import combinations, permutations
>>>
>>> l = ['combinations', 'permutations']
>>> for i in l:
... print(list(globals()[i]([1, 2, 3], 2)))
...
[(1, 2), (1, 3), (2, 3)]
[(1, 2), (1, 3), (2, 1), (2, 3), (3, 1), (3, 2)]
import math l globals()["math.sqrt"](4)
