empty list

Question

How many items are on this list?
[2,]

3
1
2

Answer 1

right now python wants to use the comma to separate list items, soit is not an item itself. you can make it one by changing your list to this:

[2, ',']

In that example the 2 is an integer and the comma is a string character. You can dothe same in the following example except the 2 will now be treated as a string just like the comma.

['2', ',']

either way you choose you must separate all items with a comma.

Answer 2

1

Answer 4

print(len([2,])) outputs 1
