如何在 python 中将一个 datetime 字符串转换为 datetime 格式,以便与另一个日期进行比较?
string_date = "2013-09-28 20:30:55.78200" abc = datetime.datetime.now() if abc > string_date : print True
You should use datetime.datetime.strptime:
datetime.datetime.strptime
import datetime dt = datetime.datetime.strptime(string_date, fmt)
fmt will need to be the appropriate format for your string. You'll find the reference on how to build your format here.
fmt
The particular format for strptime:
strptime
datetime.datetime.strptime(string_date, "%Y-%m-%d %H:%M:%S.%f") #>>> datetime.datetime(2013, 9, 28, 20, 30, 55, 782000)
