How do I call outside function from class in python

Question

How do i call an outside function from this class ?

def test(t):
   return t

class class_test():
   def test_def(q):
       test_msg = test('Hi')
       print (test_msg)

Answer 1

To call the class method, you can create an instance of the class and then call an attribute of that instance (the test_def method).

def test(t):
    return t

class ClassTest(object):
    def test_def(self):
        test_msg = test('Hi')
        print(test_msg)

# Creates new instance.
my_new_instance = ClassTest()
# Calls its attribute.
my_new_instance.test_def()

Alternatively you can call it this way:

ClassTest().test_def()

_{Sidenote: I made a few changes to your code. self should be used as first argument of class methods when you define them. object should be used in a similar manner.}
