  • python对时间日期做格式化

    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 (01 - 31)
    %H Hour in 24-hour format (00 - 23)
    %I Hour in 12-hour format (01 - 12)
    %j Day of year as decimal number (001 - 366)
    %m Month as decimal number (01 - 12)
    %M Minute as decimal number (00 - 59)
    %p Current locale's A.M./P.M. indicator for 12-hour clock
    %S Second as decimal number (00 - 59)
    %U Week of year as decimal number, with Sunday as first day of week (00 - 51)
    %w Weekday as decimal number (0 - 6; Sunday is 0)
    %W Week of year as decimal number, with Monday as first day of week (00 - 51)
    %x Date representation for current locale
    %X Time representation for current locale
    %y Year without century, as decimal number (00 - 99)
    %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');
    >>> 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'
