You did function declaration after the function call. Please follow :PEP8 for more information and secondly if take any input from user, you need to store in some variable to use any way. Here is the code that add item perfectly.

grocery_list = ['salmon', 'beef', 'eggs', 'milk']

def add_to():
 s= input("Please enter the item you'd like to add: n")
 grocery_list.append(str(s))

print(grocery_list)
question = input("Would you like to add anything to the list?: n")
if question == "yes" or "y" or "Y":
 add_to()
else:
 print("Enjoy your shopping")



print(grocery_list)

Output :

['salmon', 'beef', 'eggs', 'milk']
Would you like to add anything to the list?:
yes
Please enter the item you'd like to add: 
yourhead
['salmon', 'beef', 'eggs', 'milk', 'yourhead']

  That's another thing I wasn't struggling to figure out. Thank you! Can you explain why I need to add the (str part? Also what's the point of using n to start a new line when I don't need a new line? Is it just good in practice?

  Thanks, Okay n is for good code readability. You need to give n with input() and lets say in future if their is more confusing input user is giving which is long input and mixture of string and int, then you have to give n
