You can use the datetime
module for working with dates and times in Python. The strftime
method allows you to produce string representation of dates and times with a format you specify.
您可以使用datetime模块在Python中处理日期和时间。 strftime方法允许您使用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'

import datetime
print(
'1: test-{date:%Y-%m-%d %H:%M:%S}.txt'.format( date=datetime.datetime.now() )
)
d = datetime.datetime.now()
print('2: {:%B %d, %Y}'.format(d))

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{}的字符串中,value是当前时间。
Then rather than just displaying the raw value as {}, use formating to obtain the correct date format.
然后,不是仅将原始值显示为{},而是使用格式化来获取正确的日期格式。
