Convert a string to an external class/method API in python

Question

Is there a way to convert a string into an API call?

something like this --

import externalLib

class InternalLib():
     def function(param1='ext1'):
           #so I want it to call externalLib.ext1
           return externalLib.param1

Answer 1

You can use getattr. Check out Calling a function of a module by using its name (a string) that might help you. :)

Answer 2

You'll want to use getattr. Like so:

import externalLib

class InternalLib():
     def function(param1='ext1'):
           # Calls externalLib.ext1()
           # Omit the final () for externalLib.ext1
           return getattr(externalLib, param1)()

getattr(object, "attribute") is the same as object.attribute.
