Scenario 1: Getting a customized kernel
I have a question about getting a customized kernel on the company sponsored JupyterHub, and the answers are as following:

Open a Terminal within JupyterHub: 
Select the “New” pulldown and select “Terminal”
conda create --name 36env python=3.6
conda activate 36env
pip install numpy --user
conda deactivate
python3 -m ipykernel install --user --name 36env
Refresh the JupyterHub browser window.
Your new conda environment is now available

I need to give credit to Kenneth Reitz, who gives great instruction on this top.

Lesson 1: reproduce what Ken suggested

	
Fork Ken's github repository and make my own
	
When I am in ./sample/ folder, and try "make", it fails. Error was "OSError: [Errno 13] Permission denied: '/ddn/gs1/biotools/python/lib/python2.7/site-packages/nose'"
	
When I am in ./sample/ folder, and try "python setup.py install", it fails also. Error was " [Errno 13] Permission denied: '/ddn/gs1/biotools/python/lib/python2.7/site-packages/test-easy-install-147300.write-test'"

Topic 1: how can I solve this problem

Case: I wanted to list all the file in a directory

Under Linux, Python3

import subprocess
subprocess.call(["ls", "-al"])

Case: How to create a Python Package

It is an advance topic, but I am willing to document it in case I need in the future.

First of all, there is a guide from Hitchhikers
I documented it in my Python note with pass word

My note:

I am trying to use PyCharmEde (PCE) incorporating docker on a Django webdev project.

Python teaching note

Found a very useful tutor web for teaching Python
I need a teaching platform and found 
this one at MIT

Here are a few python doc with high regards.

Official python3 online doc

I am trying to create a workable environment for data analysis. Now on my list I have the following to be installed on my windows machine

Anaconda (maybe conda also)

I installed the Anoconda(v1.4.0) on the user level

Jupyter

I followed the link and installed jupyter
I can launch "jupyter notebook" and see the web on localhost:8888,
But, I do not see the coding environment available

Zipline

It is a little bit into it to get zipline installed. So, I tested using conda with “sub-environment”. zipline only works with python2.7!!

C:\Users\li11>conda create -n ForZipline python=2.7 biopython
(ForZipline) C:\Users\li11>conda intall -c Quantopian zipline

Using jupyter

Thank goes to our system admin and Anaconda. Both Python2 and Python3 have been installed on my windows machines. Now I can launch the “jupyter” directly. From now on, I will stick with the jupyter IDE (Interactive Development Environment).
