There seems to be an issue with Python Basics Challenge Task 4 of 4. Whenever I get to the final step it errors out

Holla,

Here is how the test work.

Task 1. Run test on task 1. Success. Task 2. Run test 1 AND 2 Success Task 3. Run test 1, 2, AND 3. Success Task 4. Run test 1 , 2, 3 AND 4 Fail - Test 1 is not passing. Tests stop and exit and tell you test 1 is no longer passing.

The reason TASK 1 is failing on TASK 4 is because your code is not compiling. You have a syntax error that keeps the code from compiling. Which means that when TASK 1 test 1 runs before it gets to TASK 2, 3 and 4. It fails. Since the code never compiled. So as far as the code is concerned. Task 1 is failing.

>>> greeting = greeting_list.split(' ')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'list' object has no attribute 'split'

See, list has no split() method. So the code is failing.

the KEY is JOIN. You need to JOIN it back into a string. You do this with .join.

ANSWER

full_name = 'Ashley Elizabeth Knowles-Swingle'
name_list = full_name.split(' ')
greeting_list = "Hi, I'm Treehouse".split(' ')
greeting_list[len(greeting_list) - 1] = name_list[0]
greeting = " ".join(greeting_list)

See, you say " " as this is where you want to join the words together. On spaces. Then .join will join the list back to a string on the spaces What list is that to join? The greeting_list.

See greetings is a a List indicated by the []. But after I join the string on the spaces with .join. You can see it returns greetings which is a string indicated by the ""

>>> greeting_list
['Hi,', "I'm", 'Ashley']
>>> greeting = " ".join(greeting_list)
>>> greeting
"Hi, I'm Ashley"
>>>

Does this help you, let me know and I can try a different approach.
