Negative Indexation

You can access characters in a string using negative indexing, which starts from the end of the string.

This is especially useful when you want to get the last character or work backwards, without manually counting the total length of the string.

Syntax

python

Negative indexing starts at -1. string[-1] returns the last character, string[-2] returns the second-to-last, and so on. string[-0] is the same as string[0] (first character), so it's rarely used.

Example

123
document = "Invoice #34567" last_char = document[-1] print(last_char) # Output: 7
copy

In this case, we don't need to count the total number of characters to find the last one. We simply use -1 to get the final digit of the invoice number.

You are working with a financial record string. Use negative indexing to extract:

  1. The last character of the string;
  2. The second-to-last character.

Assign them to the variables last_char and second_last_char, respectively.
