3,032 PointsCombo strings problem
Hello. I'm having some difficulty solving this problem as if I switch what goes into my function it works. However, the problem set says anything can be pasted into the function. What I have does not work because my string cannot be interpreted as an integer, furthermore, I don't have any control on what could be passed. Pretty lost as to where to go from here. I've done some reading on 'zip' but I want to try and figure this out using enumerate.
# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]
def combo(item1, item2):
mylist = []
for x in enumerate(item1, start=item2[0]):
mylist.append(x)
print(mylist)
myList = [1, 2, 3]
myString = "abc"
combo(myList, myString)

To reduce complexity of your solution, use a regular for loop that iterates through 0 to N-1, where N is len(item1) (item1 and item2 are of the same length)
On every iteration, append a newly generated tuple to the accumulating list, then after the loop, return the list
def combo(iter1, iter2):
combo_list = []
for i in range(len(iter1)):
combo_list.append((iter1[i], iter2[i]))
return combo_list
