最后打印第一个变量（index = 0）

Question

I'm trying to attach the first element of comma separated strings at the end. If user inputs 'first, second, third' then it should return ['first', 'second', 'third', 'first']

So I'm really close to completing it but my code returns ['first', 'second', 'third] first

I was thinking of using .append() first and then print the code. Can somebody elaborate on .append()?

s = input('Please enter a series of comma-separated strings: ')
l = s.split(",")
print(l,l[0])

Answer 1

the append() function allows a user to add a value to the end of a list. So if your list is ["hi", 1, "hello"] and we do a my_list.append(100) the new list will be come ["hi", 1, "hello", 100]

for your case all you need to do is read the values into the list as you are doing split it and then

s = input('Please enter a series of comma-separated strings: ')
l = s.split(",")
l.append(l[0])
print(l)

Your list will be in the proper format now.
