in python3 I can't say diff.days diff =start_time - another_time print(diff)

diff =start_time - another_time
print(diff)

there is no days method for diff however it prints the diff: 10543 days, 7:54:55.054150

In timedelta objects, days is a read-only attribute, not a method:

import datetime
d = datetime.timedelta(days=365, hours=15)
print(d)
print(d.days)

Results in:

365 days, 15:00:00
365

The print diff invokes the timedelta.__str__() method which "Returns a string in the form [D day[s], ][H]H:MM:SS[.UUUUUU], where D is negative for negative t."
