初学者，求一程序润色

2009-11-15 13:20:19 来自: 凌虚|advance(united & dialectical mind)

我是高中生，今年高三。这个是本人暑假时做英语阅读使用的秒表(2009年8月3日制作)。凭直觉觉得这个程序有瑕疵，但自己发现不了。所以来到这里，望高手赐教。
（使用方法：回车开始，再回车停止，再回车重新开始……。输入非空字符串回车结束。其实这个程序好理解）

from time import clock
clak1,clak2,tmstr,flag=0,0,'',False

while not tmstr:
tmstr = raw_input() # Just wait it
clak2=clock() # Get current time (in milliseconds)
# may use
# from ctypes import windll
# clak2 = windll.kernel32.GetTickCount()
# or
# clak2 = windll.winmm.timeGetTime()
# as well,
# but using the time module makes the program platform-independent
# so I chose the latter one. the data processing is different, of course.
if flag and not tmstr:
el=clak2-clak1 # el stands for elapsed time
hr=int(el/3600)
el%=3600
minit=int(el/60)
el%=60
sec=int(el)
# el may suffered a lot from float processing so I recalculated
# i don't know if it's necessary to do that
# is there anybody who can help me?
millisec=((clak2-clak1)%1)*1000
print "%ihr %i' %i'' %f" % (hr, minit, sec, millisec)
flag = False
else:
clak1, flag=clak2, True

前两句是要说明什么？

其实raw_input(‘prompt=')可以带个参数，用作提示语

import time

def timing():
raw_input('press Entern to begin.')
begin = time.time() # record begin time
raw_input('Begin timing, press Enter to end timing.')
cost = time.time() - begin
secs, mins = cost%60, cost//60
mins, hours = mins%60, mins//60
# if you want days
# hours, days = hours%24, hours//24
print 'cost time>>%dh:%dm:%ds' % (hours, mins, secs)

while True:
timing()
ask = raw_input('do you want quit(yes/no)?')
if ask.lower().count('y'):
break
