Since there are no more characters before index 0, Python "redirects" the cursor to the end of the string where characters are read right to left. If a string has length n , then the maximum index boundary is n-1 and the minimum index boundary is -n which returns the same character as index 0, namely the first character.
This range over L represents every character of T that has a suffix beginning with a. The next character to look for is r. The new range is [C[r] + Occ(r, start-1) + 1 .. C[r] + Occ(r, end)] = [10 + 0 + 1 .. 10 + 2] = [11..12], if start is the index of the beginning of the range and end is the end. This range over L is all the characters of T ...
The variable z is used to hold the length of the longest common substring found so far. The set ret is used to hold the set of strings which are of length z. The set ret can be saved efficiently by just storing the index i, which is the last character of the longest common substring (of size z) instead of S[i-z+1..i].
A prefix of S is a substring S[1..i] for some i in range [1, l], where l is the length of S. A suffix of S is a substring S[i..l] for some i in range [1, l], where l is the length of S. An alignment of P to T is an index k in T such that the last character of P is aligned with index k of T.
The mapping of characters to code-points and back can be implemented in a number of ways. The simplest approach (akin to the original Luhn algorithm) is to use ASCII code arithmetic. For example, given an input set of 0 to 9 , the code-point can be calculated by subtracting the ASCII code for '0' from the ASCII code of the desired character.

The loop at the center of the function only works for palindromes where the length is an odd number. The function works for even-length palindromes by modifying the input string. The character '|' is inserted between every character in the inputs string, and at both ends. So the input "book" becomes "|b|o|o|k|".
