Challenge Task 4 of 4: Greeting variable joining my greeting list back into a string.

Hi Team Python,

I'm stuck on this last line for my final task of the challenge where I need to take the greeting variable and join the greeting_list back into a string, where it would read out "Hi, I'm Martel" Can someone provide help on the join argument please?

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

greeting = " ".join(greeting_list)

The join() is a string method that uses a string as the "glue" between items in a list. To join a list with a space separator use:

greeting = " ".join(greeting_list)

This is one of the unusual aspects of python. In that you would think there would be a list method that joined its items give a string. Though it doesn't look like it, this is FAST and it is preferred over using a series of ``string =+ " additional text"
