You can use the datetimemodulefor working with dates and times in Python. The strftimemethodallows you to produce string representation of dates and times with a format you specify.
您可以使用该datetime模块在 Python 中处理日期和时间。该strftime方法允许您使用您指定的格式生成日期和时间的字符串表示形式。
>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'

>>> import datetime
>>> now = datetime.datetime.now()
>>> now.strftime("%B %d, %Y")
'July 23, 2010'

#python3
import datetime
print(
'1: test-{date:%Y-%m-%d_%H:%M:%S}.txt'.format( date=datetime.datetime.now() )
)
d = datetime.datetime.now()
print( "2a: {:%B %d, %Y}".format(d))
# see the f" to tell python this is a f string, no .format
print(f"2b: {d:%B %d, %Y}")
print(f"3: Today is {datetime.datetime.now():%Y-%m-%d} yay")
1: test-2018-02-14_16:40:52.txt
1：test-2018-02-14_16:40:52.txt
2a: March 04, 2018
2a：2018 年 3 月 4 日
2b: March 04, 2018
2b：2018 年 3 月 4 日
3: Today is 2018-11-11 yay
3：今天是 2018-11-11 yay
Description:
描述：
Using the new string format to inject value into a string at placeholder {}, value is the current time.
使用新的字符串格式将值注入占位符 {} 处的字符串中，值是当前时间。
Then rather than just displaying the raw value as {}, use formatting to obtain the correct date format.
然后，不要仅将原始值显示为 {}，而是使用格式化来获取正确的日期格式。

If you don't care about formatting and you just need some quick date, you can use this:
如果你不关心格式，你只需要一些快速的约会，你可以使用这个：
import time
print(time.ctime())
