I have a file functional.py which defines a number of useful functions. For each function, I want to create an alias that when called will give a reference to a function. Something like this:
foo/functional.py
def fun1(a):
return a
def fun2(a):
return a+1
...
foo/__init__.py
from inspect import getmembers, isfunction
from . import functional
for (name, fun) in getmembers(functional, isfunction):
dun = lambda f=fun: f
globals()[name] = dun
>> bar.fun1()(1)
>> 1
>> bar.fun2()(1)
>> 2
I can get the functions from functional.py using inspect and dynamically define a new set of functions that are fit for my purpose.
But why? you might ask... I am using a configuration manager Hydra where one can instantiate objects by specifying the fully qualified name. I want to make use of the functions in functional.py in the config and have hydra pass a reference to the function when creating an object that uses the function (more details can be found in the Hydra documentation).
There are many functions and I don't want to write them all out ... people have pointed out in similar questions that modifying globals() for this purpose is bad practice. My use case is fairly constrained - documentation wise there is a one-one mapping (but obviously an IDE won't be able to resolve it).
Basically, I am wondering if there is a better way to do it!
