Python格式化日期时间的函数为datetime.datetime.strftime()；由字符串转为日期型的函数为：datetime.datetime.strptime()，两个函数都涉及日期时间的格式化字符串，列举如下：

 %a Abbreviated weekday name

 %A Full weekday name

 %b Abbreviated month name

 %B Full month name

 %c Date and time representation appropriate for locale

 %d Day of month as decimal number ( - )

 %H Hour in -hour format ( - )

 %I Hour in -hour format ( - )

 %j Day of year as decimal number ( - )

 %m Month as decimal number ( - )

 %M Minute as decimal number ( - )

 %p Current locale's A.M./P.M. indicator for 12-hour clock

 %S Second as decimal number ( - )

 %U Week of year as decimal number, with Sunday as first day of week ( - )

 %w Weekday as decimal number ( - ; Sunday is )

 %W Week of year as decimal number, with Monday as first day of week ( - )

 %x Date representation for current locale

 %X Time representation for current locale

 %y Year without century, as decimal number ( - )

 %Y Year with century, as decimal number

 %z, %Z Time-zone name or abbreviation; no characters if time zone is unknown

 %% Percent sign

举一个例子：

ebay中时间格式为‘Sep-21-09 16:34’

则通过下面代码将这个字符串转换成datetime

c = datetime.datetime.strptime('Sep-21-09 16:34','%b-%d-%y %H:%M');

#打印C
c
datetime.datetime(2009, 9, 21, 16, 34)

又如：datetime转换成字符串

datetime.datetime.now().strftime('%b-%d-%y %H:%M:%S');

'Sep-22-09 16:48:08'
