推荐答案

您可以使用 dateutil.parser.parse 来将字符串解析为日期时间对象.

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，则可以使用

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)
