我在Python中看到了很多关于将日期字符串转换为datetime对象的内容,但我想采用另一种方式。 我有
datetime.datetime(2012, 2, 23, 0, 0)
我想把它转换成'2/23/2012'这样的字符串。

当前回答
我已经使用此方法将日期插入JSON对象
my_json_string = json.dumps({'date_of_birth': '''{}'''.format(date_of_birth)})
其他回答
另一个选择:
import datetime
now=datetime.datetime.now()
now.isoformat()
# ouptut --> '2016-03-09T08:18:20.860968'
到目前为止最性感的版本是格式字符串。
from datetime import datetime
print(f'{datetime.today():%Y-%m-%d}')
一种距离现在有多远的方法
通过传入参数li来支持不同的语言,这是一个对应的时间戳列表。
from datetime import datetime
from dateutil import parser
t1 = parser.parse("Tue May 26 15:14:45 2021")
t2 = parser.parse("Tue May 26 15:9:45 2021")
# 5min
t3 = parser.parse("Tue May 26 11:14:45 2021")
# 4h
t4 = parser.parse("Tue May 26 11:9:45 2021")
# 1day
t6 = parser.parse("Tue May 25 11:14:45 2021")
# 1day4h
t7 = parser.parse("Tue May 25 11:9:45 2021")
# 1day4h5min
t8 = parser.parse("Tue May 19 11:9:45 2021")
# 1w
t9 = parser.parse("Tue Apr 26 11:14:45 2021")
# 1m
t10 = parser.parse("Tue Oct 08 06:00:20 2019")
# 1y7m, 19m
t11 = parser.parse("Tue Jan 08 00:00:00 2019")
# 2y4m, 28m
# create: date of object creation
# now: time now
# li: a list of string indicate time (in any language)
# lst: suffix (in any language)
# long: display length
def howLongAgo(create, now, li, lst, long=2):
dif = create - now
print(dif.days)
sec = dif.days * 24 * 60 * 60 + dif.seconds
minute = sec // 60
sec %= 60
hour = minute // 60
minute %= 60
day = hour // 24
hour %= 24
week = day // 7
day %= 7
month = (week * 7) // 30
week %= 30
year = month // 12
month %= 12
s = []
for ii, tt in enumerate([sec, minute, hour, day, week, month, year]):
ss = li[ii]
if tt != 0:
if tt == 1:
s.append(str(tt) + ss)
else:
s.append(str(tt) + ss + 's')
return ' '.join(list(reversed(s))[:long]) + ' ' + lst
t = howLongAgo(t1, t11, [
'second',
'minute',
'hour',
'day',
'week',
'month',
'year',
], 'ago')
print(t)
# 2years 4months ago
通过直接使用datetime对象的组件,可以将datetime对象转换为字符串。
from datetime import date
myDate = date.today()
#print(myDate) would output 2017-05-23 because that is today
#reassign the myDate variable to myDate = myDate.month
#then you could print(myDate.month) and you would get 5 as an integer
dateStr = str(myDate.month)+ "/" + str(myDate.day) + "/" + str(myDate.year)
# myDate.month is equal to 5 as an integer, i use str() to change it to a
# string I add(+)the "/" so now I have "5/" then myDate.day is 23 as
# an integer i change it to a string with str() and it is added to the "5/"
# to get "5/23" and then I add another "/" now we have "5/23/" next is the
# year which is 2017 as an integer, I use the function str() to change it to
# a string and add it to the rest of the string. Now we have "5/23/2017" as
# a string. The final line prints the string.
print(dateStr)
产出——> 5/23/2017
你可以用下面的方法将datetime转换为字符串:
from datetime import datetime
date_time = datetime(2012, 2, 23, 0, 0)
date = date_time.strftime('%m/%d/%Y')
print("date: %s" % date)
以下是一些可以用来将datetime转换为字符串的模式:
