Please is there a simpler script to solve this challenge

I feel my script is too long or complicated to return a list of tuples from L and S

zippy.py 
# combo(['swallow', 'snake', 'parrot'], 'abc')
# Output:
# [('swallow', 'a'), ('snake', 'b'), ('parrot', 'c')]
# If you use list.append(), you'll want to pass it a tuple of new values.
# Using enumerate() here can save you a variable or two.
def combo(L,S):
    X = []
    B = []
    i = 0
    while i < len(L):
        X.append(L[i])
        X.append(S[i])
        t = tuple(X)
        B.append(t)
        X.remove(L[i])
        X.remove(S[i])
        i = i + 1
    return B

This is a simpler method for the same result:

def combo(list, string):
    result = []
    for i, item in enumerate(list):
        result.append((item, string[i]))
    return result

Well the simplest way would be to use the zip function but that may negate the point of the exercise.

You should a) not use zip in the exercise ;) and b) link to Python 3 docs instead of Python 2.

Good catch on the python 2 docs. And yep, zip kinda eliminates the purpose of the exercise. That's what I get for answering questions before waking up the brain :P

PS You look familiar. Wonder if I've seen you at a board game night or tech meetup in Portland.
