python - Using an index to get an item

Question

I have a list in python ('A','B','C','D','E'), how do I get which item is under a particular index number?

Example:

• Say it was given 0, it would return A.
• Given 2, it would return C.
• Given 4, it would return E.

Answer 1

What you show, ('A','B','C','D','E'), is not a list, it's a tuple (the round parentheses instead of square brackets show that). Nevertheless, whether it to index a list or a tuple (for getting one item at an index), in either case you append the index in square brackets.

So:

thetuple = ('A','B','C','D','E')
print thetuple[0]

prints A, and so forth.

Tuples (differently from lists) are immutable, so you couldn't assign to thetuple[0] etc (as you could assign to an indexing of a list). However you can definitely just access ("get") the item by indexing in either case.
