Learning Python

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:

Using Python

Recommended packages and tools for different tasks

Developer Tools

  • PyCharm
  • 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)

Date Data

String Formatting

Image Manipulation

  • Use Pillow, the Python2/3 fork of Python Image Library (PIL).

Fun examples:

Text Processing

See Text processing notes.

Graphing

Easy Graphics

Games

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)
  • Some sort of Web Server Gateway Interface (WSGI). Options include:
    • Flask (can run on Apache with Passenger, but needs its own domain name)
    • CherryPy

Examples and resources:

Notes on flask:

   $ touch tmp/restart.txt         # reload your program

Using Passengers on Dreamhost:

Python Installation

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..
