On parsing datetime, ValueError: time data does not match format

I have date time in the format YYYY/DOY/HHMM

DOY = Day of year

I tried to parse as follows.

from datetime import datetime
s = "1929/189/1820"
res = datetime.strptime(s, "%y/%j/%H%M")
print (res)

ValueError: time data ‘2029/199/1820’ does not match format ‘%y/%j/%H%M’.

>Solution :

The Y for year should be capitol

This should fix it.

datetime.strptime(s, "%Y/%j/%H%M")
