python - Issue with importing my classes

Question

Consider that I have 3 files.

I am trying to put different import function in one file and call that file i.e., File2 in this case directly.

File1.py

class generalTools(): 
     def waitAppear():
         wait()

File 11.py

class machinedata():
     def max():
         maxtime()

File2.py

import File1
import File11
self.generalTools = File1.generalTools()
self.machinedata=machinedata.max()

File3.py

from File2 import *

Note here I am not creating an object; just trying to call File1->waitAppear()

self.generalTools.waitAppear(self)

Whenever I execute above code, it throws error saying "generaTool has no instance" What's wrong with the above code?
