Checking for overlap between time spans

Question

I have a list of time entries (HHMM format) with a start time and a stop. I\'m having trouble figuring out how to code it in Python where it returns if there\'s an overlap o

Answer 1

Simple way to do it:

I change the number into string since entry 3 contains 0900, which is invalid.

entry01 = ('1030', '1245')
entry02 = ('1115', '1300')

entry03 = ('0900', '1030')
entry04 = ('1215', '1400')

def check(entry01, entry02):
    import itertools
    input_time_series = list(itertools.chain.from_iterable([entry01, entry02]))
    if input_time_series != sorted(input_time_series):
        return False
    return True

>>> check(entry01, entry02)
False
>>> check(entry03, entry04)
True
