计算时间-1到时间-2之间的时间？

Question

enter time-1 // eg 01:12
enter time-2 // eg 18:59

calculate: time-1 to time-2 / 12 
// i.e time between 01:12 to 18:59 divided by 12

如何在Python中完成.我是初学者,所以我真的不知道从哪里开始.

编辑补充:我不想要一个计时器.用户手动输入时间-1和时间2.

在此先感谢您的帮助.

Answer 1

在datetime与timedelta从内置类datetime模块是你所需要的.

from datetime import datetime

# Parse the time strings
t1 = datetime.strptime('01:12','%H:%M')
t2 = datetime.strptime('18:59','%H:%M')

# Do the math, the result is a timedelta object
delta = (t2 - t1) / 12
print(delta.seconds)

Answer 2

最简单和最直接的可能是这样的:

def getime(prom):
  """Prompt for input, return minutes since midnight"""
  s = raw_input('Enter time-%s (hh:mm): ' % prom)
  sh, sm = s.split(':')
  return int(sm) + 60 * int(sh)

time1 = getime('1')
time2 = getime('2')

diff = time2 - time1

print "Difference: %d hours and %d minutes" % (diff//60, diff%60)

例如,典型的运行可能是:

$ python ti.py 
Enter time-1 (hh:mm): 01:12
Enter time-2 (hh:mm): 18:59
Difference: 17 hours and 47 minutes

这是计时码执行的计时器.也许你可以将它用于你想要的东西.time()返回自1970-01-01 00:00:00以来的当前时间(以秒为单位)和微秒.

from time import time
t0 = time()
# do stuff that takes time
print time() - t0
