<s>[INST] Calling a function of a module from a string with the function's name in Python What is the best way to go about calling a function given a string with the function's name in a Python program.  For example, let's say that I have a module foo, and I have a string whose contents are "bar". What is the best way to go about calling foo.bar()?
I need to get the return value of the function, which is why I don't just use eval. I figured out how to do it by using eval to define a temp function that returns the result of that function call, but I'm hoping that there is a more elegant way to do this.
 [/INST] Assuming module foo with method bar:
import foo
methodToCall = getattr(foo, 'bar')
result = methodToCall()

As far as that goes, lines 2 and 3 can be compressed to:
result = getattr(foo, 'bar')()

if that makes more sense for your use case.  You can use getattr in this fashion on class instance bound methods, module-level methods, class methods... the list goes on.
