String indexing in Python is zero-based: the first character in the string has index 0, the next has index 1, and so on. The index of the last character will be the length of the string minus one. For example, a schematic diagram of the indices of the string 'foobar' would look like this: String Indices.

Python list indices start at 0 and go all the way to the length of the list minus 1. You can also access items from their negative index.
