Python 2.7 - Classes

I'm trying to edit a library in python (perfmon) - the file is session.py I want to add a module that can record some readings from a USB port. This is also my first trial with cla

Solution 1:

You can not return anything (besides None) from a class constructor.

otherwise one will get

TypeError: __init__() should returnNone

Solution 2:

as I understand in Your case answer is

>>>from perfmon import session>>>test = session.USB()

But this way You move is wrong. You should create your own module in your workspace/project dir. Import session module and Create class there

from perfmon import session
classUSB(Session):
    def__init__(self):   
        pass#I have changed this part as It has two errors in your example
