Python call class method from iterable value in for loop

Question

Say have a simple class as follows:

class Test:
    some_attributes

    def first_method():
        pass

    def second_method():
        pass

Now lets say I have put the list of methods in a list like so: methods=['first_method', 'second_method']

The question that has perplexed me is:‌ How can I‌ call the methods using the list above in a for loop. The scheme I want is like this:

for method in methods:
    Test.method

I have tried:

for method in methods:
    'Test.{}'.formats(method)

and

for method in methods:
    vars()['Test.{}'.formats(method)]

How can I achieve this concept?

Are `first_method` and `second_method` part of `Test`? Please show them as such in the question? — tituszban, Sep 20 '19 at 13:49
`first_method` and `second_method` are precisely the name of the methods defined on the Test classed. — Amir Afianian, Sep 20 '19 at 13:51
Yes, but your question shows them as separate methods *outside* of the Test class. — tituszban, Sep 20 '19 at 13:52

You can use the getattr Python method, to call methods by name:

class Test:

    def first_method(self):
        print("1")

    def second_method(self):
        print("2")


test = Test()

methods=['first_method', 'second_method']

for method in methods:
    getattr(test, method)()
