srt.join

how do i get it to join

greeting_list.py 
str = " "
full_name = "monroe swensen"
name_list = str.split(full_name)
greeting_list = str.split("Hi, I'm Treehouse")
greeting_list[2] = name_list[0]
greeting = str.join(greeting_list)

full_name = "monroe swensen"
name_list = list(full_name.split())
greeting_list = list("Hi, I'm Treehouse".split())
greeting_list[2] = name_list[0]
greeting = " ".join(greeting_list)

the reason why your code is failing is the str variable you created. the instructions say that you want to create a list separated on the whitespaces. so when you are trying to call the index on your name_list and greeting_list there are no index, because you never made it into a list. also for the joining them part. remember that you have to tell it where you will be joining them. so in this case you are joining them at the spaces so you write " ".join(greeting_list)

let me know if any of this is still confusing. i think what messed you up the most was that you didn't turn your name into a list so there was no way to use indexes

Let's look at how to improve your code.

# str = " " #<-- Don't use built-in function names as variables renaming 
full_name = "monroe swensen"
#name_list = str.split(full_name) # <-- syntax reversed
name_list = full_name.split() # Split on white space
#greeting_list = str.split("Hi, I'm Treehouse") # <-- syntax reversed
greeting_list = "Hi, I'm Treehouse".split() # Split on white space
greeting_list[2] = name_list[0]
greeting = " ".join(greeting_list) # <-- variable not needed.
