rindex 1.1.1

rindex() function for sequences

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.
