Quick Start
Running wordcount.py
Set up a directory that contains the file gp.py and a
second script called wordcount.py which contains this
code:
# always start like this
from gp import *
import sys
# supporting routines can go here
def tokens(line):
for tok in line.split():
yield tok.lower()
#always subclass Planner
class WordCount(Planner):
wc = ReadLines('corpus.txt') | FlattenBy(by=tokens) | Group(by=lambda x:x, reducingWith=ReduceToCount())
# always end like this
if __name__ == "__main__":
WordCount().main(sys.argv)
Then type the command:
% python tutorial/wordcount.py --store wc
After a couple of seconds it will return, and you can see the wordcounts with
% head wc.gp
