I've reviewed these resources and highly recommend them.
If you have never programmed with Python before, you may want to start with DataCamp's Learn python by example:
If you want to just read, I recommend starting with the Python Tutorial:
If you have not programmed before, you may try:
If you have programmed before, at this point I recommend:
- Official Python Documentation. Just read the documentation. Honestly.
- Python Tips (book, online for free)
- Python Google Style Guide.
Recommended packages and tools for different tasks
- Jupyter Notebook
Numerical Data Processing
- numpy - numeric analysis in python (needed for matplotlib)
- pandas or SparkSQL
- tabulate - create tables easily (but see my tytable replacement)
- https://pyformat.info --- Big how-to on using the % and .format() formatting
- Use Pillow, the Python2/3 fork of Python Image Library (PIL).
- matplotlib - a handy system for plotting in python. (Short example of using matplotlib within jupyter)
- Altair: Declarative Visualization in Python
- geopy - geocoding for Python
- Seaborn. (See Datacamp Tutorial)

Python contains built-in support for SQLite3.
For using MySQL, you'll need a connector. There are many available.
Install MySQL connector on anaconda:
conda install mysql-connector-python
Then you can:
import mysql.connector as mysql c = mysql.connect(host=host,database=db,user=user,password=password)
I generally prefer PyMySQL, as it's pure-python and has fewer dependencies.
Python GUI Options
I need to write some programs that use GUI.
- pyqt - Use PyQT5 (it's part of Anaconda)
- FLTK, the Fast Light Toolkit
Building Web Applications
You basically have two options:
- Write a CGI script (slow, but easy. Don't use for more than 1 request every 10 seconds)
- Some sort of Web Server Gateway Interface (WSGI). Options include:
- Bottle (easy, and the whole thing runs from a single file)
- Flask (can run on Apache with Passenger, but needs its own domain name)
- Writing your own (don't do this.)
The WSGI server needs to be run from a program that receives the Port80 connections. The two ways I've done this are:
- mod_wsgi running within Apache. (This works surprisingly well and allows you to run bottle or flask side-by-side other systems)
- CherryPy (Includes its own web server and will hand off to Bottle or Flas.)
For more information, see:
- See also https://wiki.python.org/moin/WebFrameworks
If you are using anything other CGI, you need some way to tell the web server to reload your python program. (You don't need to do this with CGI---it reloads Python and your program every time you serve another request. That's why it's so slow...)
To reload your program on Dreamhost with passenger:
$ touch tmp/restart.txt # reload your program
To reload your program with mod_wsgi:
$ touch wsgi_app.py
Using Passengers on Dreamhost:
If you are using a Mac, you almost certainly want to ditch Apple's python implementation and instead install your own.
I now recommend the Anaconda Python distribution, because it has almost everything that you need, and it's easy to add new modules.
If you want to write a Python program with a GUI that can be run on any system, you'll need to use Tkinter (Python's Tcl/Tk bindings). If you want to actually enjoy what you are writing, you want to use PyQT5..
