One Liner solution in Speedy category for Double Substring by zgoldstein
def double_substring(line):
"""
length of the longest substring that non-overlapping repeats more than once.
"""
return max([
len(line[i:j])
for i in range(len(line))
for j in range(i+1, len(line)+1)

#These "asserts" using only for self-checking and not necessary for auto-testing
assert double_substring('aaaa') == 2, "First"
assert double_substring('abc') == 0, "Second"
assert double_substring('aghtfghkofgh') == 3, "Third"
print('"Run" is good. How is "Check"?')
