First solution in Clear category for Long Non Repeat by arbores401
def non_repeat(line):
"""
the longest substring without repeating chars
"""
ls = [line[i:j] for i in range(len(line))
for j in range(i+1, len(line)+1)
if len(set(line[i:j])) == j - i]
return max(ls, key=len, default='')

#These "asserts" using only for self-checking and not necessary for auto-testing
assert non_repeat('aaaaa') == 'a', "First"
assert non_repeat('abdjwawk') == 'abdjw', "Second"
assert non_repeat('abcabcffab') == 'abcf', "Third"
print('"Run" is good. How is "Check"?')
