Thesis working hours

A Python script follows, that shows the working hour statistics.

import sys
from subprocess import *

p1 = Popen(["git", "log"], stdout=PIPE)
p2 = Popen(["grep", "^Date"], stdin=p1.stdout, stdout=PIPE)
p3 = Popen(["awk", "{printf \"%d \", $5}"], stdin=p2.stdout, stdout=PIPE)
output = p3.communicate()[0]
hours = output.split()
stats = {}
for h in range(0,24):
    stats[h] = 0
for h in hours:
    stats[int(h)] += 1
for k in stats.keys():
    print "%02d: %s" % (k, "*"*stats[k])

And the results...
