Strptime() function won't give full python datetime-CodePudding

I have the following datetime which I'm trying to convert into a datetime object.

BEGINDATE = '20211121 09:00:00.000' 
start_date = datetime.strptime(BEGINDATE, "%Y%m%d %H:%M:%S.%f")

I expect to see an output like when I run datetime.now(), i.e.

datetime.datetime(2022, 4, 11, 9, 28, 45, 447007)

Instead, I get the following

datetime.datetime(2021, 11, 21, 9, 0)

It cuts out two of the time arguments and also displays the minutes as 0 rather than 00. Have I formatted it wrong?

CodePudding user response：

I you try with non zero values like this:

BEGINDATE = '20211121 09:01:02.120' 
start_date = datetime.strptime(BEGINDATE, "%Y%m%d %H:%M:%S.%f")

you get:

 datetime.datetime(2021, 11, 21, 9, 1, 2, 120000)

so the the script is correct and the problem is in the data.
