First solution in Clear category for Create Intervals by vnkvstnk
from itertools import count, groupby
def create_intervals(data):
key_func = lambda x, c = count(): x - next(c)
grouped_data = [list(x) for _, x in groupby(sorted(data), key=key_func)]
return [(min(x), max(x)) for x in grouped_data]
if __name__ == '__main__':
#These "asserts" using only for self-checking and not necessary for auto-testing
assert create_intervals({1, 2, 3, 4, 5, 7, 8, 12}) == [(1, 5), (7, 8), (12, 12)], "First"
assert create_intervals({1, 2, 3, 6, 7, 8, 4, 5}) == [(1, 8)], "Second"
print('Almost done! The only thing left to do is to Check it!')
