1) pad string to even number of chars 2) use textwrap to split into 2-char elements solution in Clear category for Split Pairs by leggewie
from textwrap import wrap
def split_pairs(a):
b=a.ljust((len(a)+(len(a)%2)),"_") # pad the string to an even number of chars with _ as necessary
return wrap(b,2) # split string into elements of 2 chars each
if __name__ == '__main__':
print("Example:")
print(list(split_pairs('abcde')))
# 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('')) == []
