“ takes no arguments (1 given)” but I gave none

Question

I am new to Python and I have written this simple script:

#!/usr/bin/python3
import sys

class Hello:
    def printHello():
        print(\'Hello!\')

def ma         


        

Answer 1

The error is referring to the implicit self argument that is passed implicitly when calling a method like helloObject.printHello(). This parameter needs to be included explicitly in the definition of an instance method. It should look like this:

class Hello:
  def printHello(self):
      print('Hello!')
