Question

If I have more than one class in a python script, how do I call a function from the first class in the second class?

Here is an Example:

Class class1():

  def function1():
        blah blah blah

Class class2():

 *How do I call function1 to here from class1*

Answer 1

Functions in classes are also known as methods, and they are invoked on objects. The way to call a method in class1 from class2 is to have an instance of class1:

class Class2(object):
    def __init__(self):
        self.c1 = Class1()
        self.c1.function1()
