rindex

This package provides rindex() function that returns last index of value in sequence.

Installing

pip install rindex

Examples

from rindex import rindex


numbers = [5, 1, 3, 8, 10, 5, 8, 1, 8, 3]

print(rindex(numbers, 1))  # 7

print(rindex(numbers, 8, 4, 8))  # 6

Goals

Support all features of built-in .index()
Speed
Portability (support for different platforms)

Supported platforms

Currently, the library includes three rindex() implementations:

Cython
Pure Python (when the Cython one is not available; slower)
Pure Python for PyPy

Features

Supports any sequences
Supports start and stop (both may be negative or out of bounds)
Doesn't copy the sequence

Controlling Cython extensions

You can set environment variable ENABLE_RINDEX_EXTENSIONS to 0 or 1 to forcefully disable/enable Cython extensions. This can be useful if you face compilation problems and want to use pure Python version.

Benchmarking

tests/benchmark.py can generate interactive plots with comparisons of different implementations.
