Introduction

This Python package provides functions to convert integer numbers to their textual representation in the Lezgi language and vice versa. It supports numbers up to 9007199254740991 and down to -9007199254740991, which are the maximum safe integers in JavaScript/Typescript (the original language of the package).

The Lezgi language is a Northeast Caucasian language spoken by the Lezgin people in southern Dagestan and northern Azerbaijan.

Features

• Number to Lezgi Numeral Conversion: Convert integers to Lezgi text representation.
• Lezgi Numeral to Number Conversion: Convert Lezgi numerals back to integers.
• Supports Negative Numbers: Handles both positive and negative integers.
• Large Number Support: Works with very large numbers up to nonillion (1e30).
• Unit Tests Included: Comprehensive tests to ensure correctness.

Installation

To install the package, you can either download it from pypi:

pip install lezgi-numbers

Or clone this repository and install it using pip in editable mode.

git clone https://github.com/LekiTech/lezgi-numbers-py.git
cd lezgi-numbers-py
pip install -e .

Usage

The package provides two main functions:

• numToLezgi(num: int) -> str: Converts an integer to its Lezgi text representation.
• lezgiToNum(lezgi_num_str: str) -> int: Converts a Lezgi numeral string to an integer.

First, import the necessary functions:

from lezgi_numbers import numToLezgi, lezgiToNum

Converting Numbers to Lezgi Numerals

number = 1986
lezgi_numeral = numToLezgi(number)
print(lezgi_numeral)  # Output: 'агъзурни кIуьд вишни кьудкъанни ругуд'

Converting Lezgi Numerals to Numbers

lezgi_num_str = 'кьве агъзурни къанни кьуд'
number = lezgiToNum(lezgi_num_str)
print(number)  # Output: 2024

Examples

Here are additional examples demonstrating the usage of the package.

Example 1: Converting Number to Lezgi Numeral

from lezgi_numbers import numToLezgi

print(numToLezgi(700))          # Output: 'ирид виш'
print(numToLezgi(1001))         # Output: 'агъзурни сад'
print(numToLezgi(-102))         # Output: 'минус вишни кьвед'
print(numToLezgi(2024))         # Output: 'кьве агъзурни къанни кьуд'

Example 2: Converting Lezgi Numeral to Number

from lezgi_numbers import lezgiToNum

print(lezgiToNum('вишни кьвед'))           # Output: 102
print(lezgiToNum('минус вишни кьвед'))     # Output: -102
print(lezgiToNum('кьве агъзурни къанни кьуд'))  # Output: 2024

Example 3: Handling Large Numbers

from lezgi_numbers import numToLezgi, lezgiToNum

large_number = 9007199254740991
lezgi_numeral = numToLezgi(large_number)
print(lezgi_numeral)
# Output: 'кIуьд квадриллионни ирид триллионни вишни кьудкъанни цIекIуьд миллиардни кьве вишни яхцIурни цIикьуд миллионни ирид вишни яхцIур агъзурни кIуьд вишни кьудкъанни цIусад'

converted_back = lezgiToNum(lezgi_numeral)
print(converted_back)  # Output: 9007199254740991

Testing

The package includes unit tests to verify the correctness of the conversion functions.

Running Tests

python -m unittest discover -s tests  

Test Coverage

The tests cover:

• Correct conversion of numbers to Lezgi numerals.
• Correct conversion of Lezgi numerals to numbers.
• Handling of invalid inputs (e.g., non-integer numbers, invalid strings).
• Edge cases, including large numbers and negative numbers.
