# Not sure why this code challenge does not work?

Hello fellow student developers,

So I am having an issue with this code challenge. I've been at it for 2 days and I finally figured out some code that worked in the terminal running Python, and it produced the same result as the desired output in this challenge. However, the code challenge does not accept the code as valid and I receive the Bummer: Try again! message. So I am not sure as to why this code will not be accepted given that it produces the same output. Any advice would be much appreciated!! Thank you.

combo.py
```# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]

def combo(iterable1, iterable2):
list_1 = iterable1
list_2 = iterable2
new_list = []
for counter, x in enumerate(list_1):
new_tuple = (x, list_2[counter])
new_list.append(new_tuple)
return(new_list)
```
