TypeError: Missing 1 required positional argument: 'self'

Question

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\         


        

Answer 1

Works and is simpler than every other solution I see here :

Pump().getPumps()

This is great if you don't need to reuse a class instance. Tested on Python 3.7.3.
