having problems with changing "Treehouse" in greeting_list to the first item in your name_list variable.

I believe that what you're looking for, essentially, is this? Do you see how that works? Let me know. :)

full_name = ("Lisa Sparks")
name_list = full_name.split()
greeting_list = "Hi, I'm Lisa".split()
greeting_list[len(greeting_list) - 1] = name_list[0]
greeting = " ".join(greeting_list)
print (greeting)

Hi Lisa, I don't recall the exact problem but hopefully this helps. If the name_list looks like this: name_list = ['John','Jacob','Jingleheimerschmidt']

To set the variable named Treehouse to the value of the first item you must use a notation that references the index (or position). This notation for indexes of lists starts at 0 so your syntax would be something like:

Treehouse = name_list[0]

The Treehouse variable in my example would now have the value 'John'. Hope this helps!

Hello, Brian I tried your example, but It didn't work.

yes it worked thanks

Gimme a thumbs-up on the right, there? Thanks, and I'm glad I could help! :)

I got this error: Your name_list's first item doesn't seem to be in your greeting_list!

when trying to change the value of the word Treehouse in the greeting list to the value of the first item in the name list as so:

greeting_list[3] = name_list[0]

Any ideas why this throws that error? I thought I was on the right track here. Thanks for any help!

Thanks
