pip install toolib==0.1



Whenever I write a function or class I feel I'll need at some point in the future, I'll put it here.


nlp contains:

  • Tree (and its child PTree) is in an implementation of simple parse trees. They can be created manually, or from either PTB or qtree format. PTree adds probabilities to the nodes.
  • ContextFreeLanguage, which contains a CYK parser (and a method for estimating probabiities based on a PTB-like corpus). This might not be optimized for large corpora yet.

tools contains the rest. See below.


Heap is a wrapper around a list with the heapq module of the standard library that accepts a key argument, which can be used to have heaps that are sorted by something else than the standard key.

CSV is a simple wrapper for csv files. Returns namedtuples, can write from tuples. Nicer than csv.writer and csv.reader, imho. May break with some files, though, so don't use in production.


nested_loop is a simple function to avoid having to create deeply nested loops.

eprint is a convenience function that prints to stderr automatically.

getchr gets a single character from the terminal, without printing it. This gets the characters in sort of a raw format, caveats are explained in the docstring.

parametrized, and fmap are ways to give a decorator additional arguments. Please note that parametrized was not written by me.

argmap is a decorator that maps some function over all arguments, e.g. to turn them all to lowercase.

runtime is a decorator to run a function n times, and measure the time. The result of the last call is returned.

nop returns the first argument.

fuzzy_match returns the best match (if any) of an input string in a list of candidate strings. Look in the code to see what "match" means.

most is like the builtins any and all, in that it checks whether most of the iterable is truthy, and not like them in that it's kind of a joke.

limit yields the first couple of elements of an iterable (think head).
