在 Python 中将 json 字段转换为日期时间

Question

I get time data from API response like '2020-02-25T20:53:06.706401+07:00' . Now I want to convert to %Y-%m-%d %H:%M:%s format. But I do not know exactly standard format of that time data.

Help me find the time format!

Answer 1

In your case you can use datetime.fromisoformat :

from datetime import datetime

datetime_object = datetime.fromisoformat("2020-02-25T20:53:06.706401+07:00")
print(datetime_object.strftime("%Y-%m-%d %H:%M:%s"))

Prints

2020-02-25 20:53:1582656786

Other options:

• Use the third party dateutil library

• Use datetime.strptime which parses the string according to format

Answer 2

You can convert to a datetime object and then optionally recreate the string in a new format as follows:

from datetime import datetime

d = "2020-02-25T20:53:06.706401+07:00"
dt = datetime.strptime(d, "%Y-%m-%dT%H:%M:%S.%f%z")
# Note the capital S
new = dt.strftime("%Y-%m-%d %H:%M:%S")

However the new value here has lost the timezone offset information. I assume that's OK for you. I also used %S instead of %s since I assume that's really what you want. The lowercase %s wouldn't really make sense, and is also not truly supported by Python .
