I'm stuck on how to replace single items within a list with others without a big workaround.

I'm having an issue on Challenge task 3 of 3 where I just don't understand how to replace single list items from one list to another...

Hi, could you give an example of exactly what you mean?

To replace the list item:

You should point to the index of that item and then assign it to another item that you want.

For example if you want to replace letter 'c' to 'd':

list = ['a', 'b', 'c']

list[len(list)-1] = 'd'

or

list[-1] = 'd'

By the way, Fabion already gave you the correct answer to pass the challenge.

Take a look at this:

full_name = "Fabion Stephens"
name_list = full_name.split()
greeting_list = "Hi, I'm X".split()
greeting_list[-1] = name_list[0] # <-- this is how you would replace the last item in the list 
greeting = ' '.join(greeting_list) # <-- then make it a sentence again using the join method with the list as its param

Thank you both! I would've preferred the answer that Sreng gave me so that I can try again on my own, but it's good to see the full thing worked out with comments! :)
