I am writing a program that checks the next bus from a timetable obtained from the net.
I want to compare the time of the timetable string and the time of the day that can be obtained with datetime
So the time of the string is a time type? I want to convert it to, but the date information is also included.
How can I make comparisons only in time?

Applicable source code

import datetime
#str = ['06: 03 ', '06: 09', '06: 13 ', '06: 21', '06: 26 ', '06: 31', '06: 38 '...]'
now = datetime.datetime.now ()
for i in range (0,83)
    t = datetime.datetime.strptime (str [i], '% H:% M')
    if now<t:
        next = t
    break
print (next)

The date is entered in the above program.
