time data does not match format '%y-%m-%d' [closed]

Question

self.train_date = datetime.datetime.strptime(train_date,'%y-%m-%d').date()

when I run above code, I get below error

I don't get it..because I checked the date format.

Answer 1

Use Y for match YYYY format, because y is for YY format of year:

self.train_date = datetime.datetime.strptime(train_date,'%Y-%m-%d').date()
