Python Python Collections (Retired) Tuples Combo

Bummer in my code, how to fix this?

I got a "Bummer! Didn't get the right output. For example, expected (10, 'T') as the first item, got (10, 'T') instead."

What does this mean?

Also I feel my code is very manual, is there a better solution to this?

zippy.py
# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]
# If you use .append(), you'll want to pass it a tuple of new values.

ite = 1,2,3
ite2 = "a","b","c"

def combo(rr,tt):
  listo = []

  a = rr[0], tt[0]
  b = rr[1], tt[1]
  c = rr[2], tt[2]

  abc = [a,b,c]

  for i in abc:
    listo.append(i)

  return listo

combo(ite, ite2)

Here's a few hints:

  • don't call your function yourself, the challenge checker will call it
  • don't assume the sizes of the input iterables will be 3 (even though the example showed 3)
  • be sure to return only the number of tuples that can be made from the input

You probably want to use the enumerate function so you can get the index of the item in the first list, and use that to get the corresponding value from the second list.
