Not sure how to do this. The second picture is of the doctest required and all of the specific cases that must be passed. Thanks.

Goal: [5pts] Write the function joinedList(n), where n is an integer number. This functions returns (not prints) the list [1,,...2,1] for every n0 and theli n0. If an invalid input is provided, the function must return a string with an error message (the string 'error' is enough) st [n,nt1,n+2, -1, -1, -2..,] for every [5pts] Write the function removePunctuation(xt), where txt is a string. This function returns a string that replaces every character that is not an alphabet letter into a space provided as an input, the function must return a string with an enough). Hint: string method isalpha) . If a string is not Deliverables: Submit your code with the file name LAB2.py to the Lab2 GradeScope assignment before the due date Notes: Verify your code is returning and not printing the output, otherwise, your code will returrn . To provide input to your fiunctions, include -i as an argument in the command line to run . A doctest is provided in the starter code. To run it, type python -m doctest -v LAB2.py None and the test cases will fail an interactive Python session (python -i LAB2.py) Mac users type python3 def joinedList (n): >>>joinedlist (5) 11, 2, 3, 4, 5, 5, 4, 3, 2, 1] >joinedlist (-3) >>>joinedList ('5') 'error' >joinedList ([2,8, I9]1) error' >>>joinedList (0) It 1 T1 # YOU CODE STARTS HERE def removePunctuation (txt): IT TT # txt : string # It replaces every character that is not an alphabet letter # into a space, and returns it. >> removePunctuation ("I like chocolate cake!!!
