The arsenal is an assortment of python utilities that I can't live without.

There are a lot of files here. I'd like to highlight a few of my most useful / favorite things:

• iterview.py

  Progress bar for all iterables with a known length.

• math/

  Tons of math utilities

  math.compare is particularly useful for debugging numerical algorithms

• terminal/

  Utilities for making colorful and nicely formatting terminal output.

• viz/

  Utilities for making interactive plots, especially viz.util.{axman,lineplot}.

• alphabet.py

  Maintain a bijective map from "things" to unique integers.

• robust.py

  Utilities such as timelimit and retry to help "robustify" your code.

• fsutils.py

  utilities for working with the file system like atomic file writes and recursively listing directories (like UNIX find)

• debug/

  I'm a big fan of debug.utils.ip.

• cache/

  contains the memoize decorator and even a persistence shelve-based variant.
