How to understand if one time period overlaps another?

Question

Python

Hi Habr!

The question is the following
. I have two time intervals: 09:20 - 10:20 and 10:21 - 11:21

How to make it so that when entering the next time interval, it checks if it captures these intervals.
That is, what would sweep away options like 08:00 - 12:00, 09:25 - 16:00, etc.

I can’t solve the problem, please help)

Answer 1

It all depends on the library you are using. For example datetime like this:

from datetime import datetime

a = datetime(year=2020, month=1, day=1, hour=9, minute=0, second=0)
b = datetime(year=2020, month=1, day=1, hour=12, minute=0, second=0)

c = datetime(year=2020, month=1, day=1, hour=18, minute=0, second=0)

if a < c < b:
    print('In range')
else:
    print('Out of range')

Datetime objects can be compared to each other.
