program creek seems to be a good site for handy references of python modules. For e.g. when I wanted to know how to use Stratified Shuffle module, the examples shown on this page were very useful.

This code will change the standard out to a file so that jupyter notebook cell's responses are saved to a file.

import sys
oldStdout = sys.stdout
file = open('logFile', 'w')
sys.stdout = file
