# and ends at 21.

# We us group() method to get all the matches and
# captured groups. The groups contain the matched values.
# In particular:
# match.group(0) always returns the fully matched string
# match.group(1) match.group(2), ... return the capture
# groups in order from left to right in the input string
# match.group() is equivalent to match.group(0)
# So this will print "June 24"
print ("Full match: %s" % (match.group(0)))

print ("Month: %s" % (match.group(1)))
# So this will print "24"
