Question

The following code is working as expected. But I have 2 questions.

# import datetime # does not work
from datetime import datetime
row = ('2002-01-02 00:00:00.3453', 'a')
x = datetime.strptime(row[0], "%Y-%m-%d %H:%M:%S.%f")

1) Why does only import datetime does not work?

2) How do I know to which module does the ‘strptime’ method belogs to?

>>> help('modules strptime') 

does not provide the info I am looking for.

Answer 1

Either you do:

import datetime
x = datetime.datetime.strptime(row[0], "%Y-%m-%d %H:%M:%S.%f")

or you do:

from datetime import datetime
x = datetime.strptime(row[0], "%Y-%m-%d %H:%M:%S.%f")
