Python demonstration code and text files

These files were prepared by Robert Staubs for use in the UMass Linguistics Python summer group, 2009.

Example of text processing using regular expressions:

regex.py

Program to search for a pattern in the glosses of a child phonology datafile and put the matches in a new file:

csvsearch.py

File referred to in script (see Pater 1997 on source):

trevor.csv

Some background on collection types we haven't touched on much (tuples, dictionaries, sets):

collections.py

Word frequency example for dictionaries (makes a dictionary of word counts, gives a list of words sorted by frequency):

wordfrequency.py

Text we could use with the above (Through the Looking Glass and What Alice Found There):

ttlg.txt

Basic function example, Sanskrit meter generation, Fibonacci in 3 different ways (closed form, recursive by way of Sanskrit meters, and the memoization one--should be doable after word frequency):

functions.py

Some information about dynamic programming, Fibonacci, and its relation to Sanskrit meter, in the context of a discussion of Tesar’s (1995) Gen:
