What is getattr() exactly and how do I use it?

Question

I\'ve recently read about the getattr() function. The problem is that I still can\'t grasp the idea of its usage. The only thing I understand about getattr() is

Answer 1

I think this example is self explanatory. It runs the method of first parameter, whose name is given in the second parameter.

class MyClass:
   def __init__(self):
      pass
   def MyMethod(self):
      print("Method ran")

# Create an object
object = MyClass()
# Get all the methods of a class
method_list = [func for func in dir(MyClass) if callable(getattr(MyClass, func))]
# You can use any of the methods in method_list
# "MyMethod" is the one we want to use right now

# This is the same as running "object.MyMethod()"
getattr(object,'MyMethod')()
