Not working!

Hi,
I used your code on my machine, but I am facing some error:
line 34, in
from stochastic_functions import *
ModuleNotFoundError: No module named 'stochastic_functions'

This is the error shown on my interpreter.
Second thing I want to know, this code is used for all type of quantitative methods?
Waiting for your response! :)
