List comprehension solution in Uncategorized category for Split Pairs by akamus
def split_pairs(a):
if len(a) % 2 == 1:
a += '_'
return [a[i-2] + a[i-1] for i in range(2, len(a) + 1) if i % 2 == 0]
if __name__ == '__main__':
# print("Example:")
# print(list(split_pairs('abcd')))
# These "asserts" are used for self-checking and not for an auto-testing
assert list(split_pairs('abcd')) == ['ab', 'cd']
assert list(split_pairs('abc')) == ['ab', 'c_']
assert list(split_pairs('abcdf')) == ['ab', 'cd', 'f_']
assert list(split_pairs('a')) == ['a_']
assert list(split_pairs('')) == []
