Combos challenge output seems correct but not passing
When I run this in workspace it seems fine, but it fails the challenge. What am I doing wrong?
def combo(keys,value_string): tup_list = for key in keys: tup = key, value_string[key-1] tup_list.append(tuple(tup)) return tup_list

Your solution seems to bank on the
keys array being exactly as in the sample data. This is an incorrect assumption. The data used to grade the challenge is not guaranteed to be the same as the sample data. Your solution needs to be more generic to handle any data, such as,
combo(['a', 'b', 'c', 'd'], ['Z', 'Y', 'X', 'W']).
Try using a generic index to build each tuple, such as:
for index in range(len(keys)): tup = keys[index], value_string[index] # OR for index, key in enumerate(keys): tup = key, value_string[index]
