推荐答案

您可以使用 dateutil.parser.parse 将字符串解析为datetime对象。

You can use dateutil.parser.parse to parse strings into datetime objects.

dateutil.parser.parse 将尝试猜测字符串的格式，如果您事先知道确切的格式，那么您可以使用 datetime.strptime 格式字符串（见Brent Washburne的答案）。

dateutil.parser.parse will attempt to guess the format of your string, if you know the exact format in advance then you can use datetime.strptime which you supply a format string to (see Brent Washburne's answer).

from dateutil.parser import parse

a = "2012-10-09T19:00:55Z"

b = parse(a)

print(b.weekday())
# 1 (equal to a Tuesday)
