I am not sure how to solve this, can Someone walk me through this step by step
Alright, this one can be tricky but I'm sure you can do it.
Create a function named combo that takes two ordered iterables. These could be tuples, lists, strings, whatever.
Your function should return a list of tuples. Each tuple should hold the first item in each iterable, then the second set, then the third, and so on. Assume the iterables will be the same length.
Check the code below for an example.
I cannot figure out what to do, I can easily just find the answers online but I still don't understand why they do what they did. Can someone please take the time and explain to me step by step what, why, and how. I would very much appreciate it
# combo([1, 2, 3], 'abc') # Output: # [(1, 'a'), (2, 'b'), (3, 'c')] def combo (iterable1, iterable2): for index, x in enumerate(iterable1):

I'm sure there are a million way to solve this, but here's what I chose to do.
def combo(iterable1, iterable2): tuples_list = #Create an empty list to store the tuples we'll create in. #Assuming equal lengths, we're going to create an index for each element in both iterables for idx in range(0, len(iterable1)): #using the indexs we created, we can access that index on both iterables, and append it to the tuples_list. this could also be done in two parts, creating a variable named 'tuple' and then appending that, that's your choice. tuples_list.append((iterable1[idx], iterable2[idx])) return tuples_list #return our filled in list
As you're clearly curious enough to actually want to know how this works, I'd recommend when you finish this course ou look into the more pythonic method 'zip'
#this won't pass the challenge, but it's the way you'd normally solve this def combo(iterable1, iterable2): return list(zip(iterable1, iterable2))
Let me know if you need any more clarifications
