TypeError: Missing 1 required positional argument: 'self'

I can't move beyond the mistake:

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 sole thing I can consider is that python 3.3 requires a special syntax.

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

        pass  # dummy code



p = Pump.getPumps()



print(p)

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