TypeError: Missing 1 required positional argument: 'self'

I am new to python and have hit a wall. I followed several tutorials but cant get past the error:

    Traceback (most recent call last):
      File "C:\Users\Dom\Desktop\test\test.py", line 7, in <module>
        p = Pump.getPumps()
    TypeError: getPumps() missing 1 required positional argument: 'self'

I examined several tutorials but there doesn't seem to be anything different from my code. The only thing I can think of is that python 3.3 requires different syntax.

main scipt:

    # test script

    from lib.pump import Pump

    print ("THIS IS A TEST OF PYTHON") # this prints

    p = Pump.getPumps()

    print (p)

Pump class:

    import pymysql

    class Pump:

        def __init__(self):
            print ("init") # never prints

        def getPumps(self):
                    # Open database connection
                    # some stuff here that never gets executed because of error

If I understand correctly "self" is passed to the constructor and methods automatically. What am I doing wrong here?

I am using windows 8 with python 3.3.2

You need to instantiate a class instance here.


    p = Pump()

Small example -

    >>> class TestClass:
            def __init__(self):
                print "in init"
            def testFunc(self):
                print "in Test Func"

    >>> testInstance = TestClass()
    in init
    >>> testInstance.testFunc()
    in Test Func
