Question

Normal way:

import ham
ham.eggs.my_func()
ham.sausage.my_func()

How I want it “Dynamic” way:

str = 'eggs'
ham.str.my_func()
str = 'sausage'
ham.str.my_funct()

Same thing, but ideally how I would use it in a loop:

for x in ['eggs', 'sausage']
    ham.x.my_func()

Basically, I want a string tell which class’s my_func to invoke?

Answer 1

getattr(ham, x).my_func()

This gets the method/thing (Python is duck typed) from ham which was assigned as an attribute whose name was the contents of x (if x is 'foo', then it’ll be ham.foo), then invokes my_func on that

If ham has no method with the right name, you’ll get an exception.

Incidentally, your example of ham.str.my_func() should be getattr(ham, str).my_func().

If you want to really do this the right way, you could use the imp method to only get members of a certain type, or use additional introspection.
