在python中获取格式化的日期时间，就像在php中一样

Getting formatted datetime in Python like in PHP

如何以与PHP相同的方式在python中获取格式化日期时间EDOCX1？0？

日期、日期时间和时间对象都支持strftime(format)方法，以创建一个表示受显式格式字符串控制的时间的字符串。

这是一个格式代码列表，其中包含它们的指令和含义。

%a Locale’s abbreviated weekday name.
%A Locale’s full weekday name.
%b Locale’s abbreviated month name.
%B Locale’s full month name.
%c Locale’s appropriate date and time representation.
%d Day of the month as a decimal number [01,31].
%f Microsecond as a decimal number [0,999999], zero-padded on the left
%H Hour (24-hour clock) as a decimal number [00,23].
%I Hour (12-hour clock) as a decimal number [01,12].
%j Day of the year as a decimal number [001,366].
%m Month as a decimal number [01,12].
%M Minute as a decimal number [00,59].
%p Locale’s equivalent of either AM or PM.
%S Second as a decimal number [00,61].
%U Week number of the year (Sunday as the first day of the week)
%w Weekday as a decimal number [0(Sunday),6].
%W Week number of the year (Monday as the first day of the week)
%x Locale’s appropriate date representation.
%X Locale’s appropriate time representation.
%y Year without century as a decimal number [00,99].
%Y Year with century as a decimal number.
%z UTC offset in the form +HHMM or -HHMM.
%Z Time zone name (empty string if the object is naive).
%% A literal '%' character.

这就是我们可以用Python中的日期时间和时间模块做的事情。

import time
import datetime

print"Time in seconds since the epoch: %s" %time.time()
print"Current date and time:" , datetime.datetime.now()
print"Or like this:" ,datetime.datetime.now().strftime("%y-%m-%d-%H-%M")

print"Current year:", datetime.date.today().strftime("%Y")
print"Month of year:", datetime.date.today().strftime("%B")
print"Week number of the year:", datetime.date.today().strftime("%W")
print"Weekday of the week:", datetime.date.today().strftime("%w")
print"Day of year:", datetime.date.today().strftime("%j")
print"Day of the month :", datetime.date.today().strftime("%d")
print"Day of week:", datetime.date.today().strftime("%A")

它将打印出如下内容：

Time in seconds since the epoch: 1349271346.46
Current date and time: 2012-10-03 15:35:46.461491
Or like this: 12-10-03-15-35
Current year: 2012
Month of year: October
Week number of the year: 40
Weekday of the week: 3
Day of year: 277
Day of the month : 03
Day of week: Wednesday

早在2003年，Simon Willison就编写了日期格式，这是一个小的日期格式转换类，可以在python中使用php样式的日期格式字符串：

1

>>> from datetime import datetime
>>> from DateFormat import DateFormat
>>> timestamp = 1354633606
>>> df = DateFormat(datetime.fromtimestamp(timestamp))
>>> df.format('M d Y')
'Dec 04 2012'
