python - python格式日期时间的问题

Question

我在格式化日期时遇到问题。这是我的代码:

myDate=datetime.datetime.now()
print myDate #2011-02-02 13:54:26.162000
stime = time.mktime(time.strptime(myDate, '%Y-%m-%d %I:%M%S.%f'))

在我的最后一行我得到了异常:

File "c:\Python27\Lib\_strptime.py", line 322, in _strptime
  found = format_regex.match(data_string)

这是怎么回事？

编辑更清楚地说，这是我的整个代码，它是我在 stackoverflow 上找到的内容的混合:

import random
import time

def strTimeProp(start, end, format, prop):
    """Get a time at a proportion of a range of two formatted times.

    start and end should be strings specifying times formated in the
    given format (strftime-style), giving an interval [start, end].
    prop specifies how a proportion of the interval to be taken after
    start.  The returned time will be in the specified format.
    """

    stime = time.mktime(time.strptime(start, format))
    etime = time.mktime(time.strptime(end, format))

    ptime = stime + prop * (etime - stime)

    return time.strftime(format, time.localtime(ptime))


def randomDate(start, end, prop):
    return strTimeProp(start, end, '%Y-%m-%d %H:%M:%S.%f', prop)

b1=datetime.datetime.now()
print b1
startDate=b1-datetime.timedelta(27375)
print startDate
endDate=b1-datetime.timedelta(6571)
print endDate
randomDate=randomDate(str(startDate), str(endDate), random.random())

我正在尝试获取成人的随机出生日期。

好吧，如果你说一个成年人的年龄可以在 18 到 75 岁之间(6571 - 27375 天)，那么让我们找出从今天算起很多天前的日期:

from datetime import datetime, timedelta
import random

birthday = datetime.today() - timedelta(days = random.randrange(6571, 27375))

print 'Person was born on %s' % (birthday.strftime('%Y-%m-%d'))
