# always start like this from gp import * import sys

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)
