Date and time ⇔ character string

From time_struct to a string, or from a string to time_struct.

python

>>> import time
>>> now = time.localtime()
>>> now
time.struct_time(tm_year=2012, tm_mon=5, tm_mday=8, tm_hour=4, tm_min=3, tm_sec=
42, tm_wday=1, tm_yday=129, tm_isdst=0)

>>> str_now = time.strftime('%c', now)
>>> str_now
'05/08/12 04:03:42'
>>> time.strptime(str_now, '%c')
time.struct_time(tm_year=2012, tm_mon=5, tm_mday=8, tm_hour=4, tm_min=3, tm_sec=
42, tm_wday=1, tm_yday=129, tm_isdst=-1)

>>> str_now = time.strftime('%Y/%m/%d %H:%M:%S', now)
>>> str_now
'2012/05/08 04:03:42'
>>> datetime.datetime.strptime(str_now, '%Y/%m/%d %H:%M:%S')
time.struct_time(tm_year=2012, tm_mon=5, tm_mday=8, tm_hour=4, tm_min=3, tm_sec=
42, tm_wday=1, tm_yday=129, tm_isdst=-1)

The format strings for time.strftime () and time.strptime () are Documentation. It seems to be the same as C language.

Others It seems that time.asctime () makes the format the same as asctime () in C language, but there seems to be no way to convert this string to struct_time.

python

>>> asctime = time.asctime()
>>> asctime
'Tue May  8 04:03:42 2012'
>>> time.strptime(asctime, '%a %b %d %H:%M:%S %Y')
time.struct_time(tm_year=2012, tm_mon=5, tm_mday=8, tm_hour=4, tm_min=3, tm_sec=
42, tm_wday=1, tm_yday=129, tm_isdst=-1)

I can't tell the difference between time and datetime, but I feel that time is fine if you don't add or subtract dates.
