simple python code to convert between arabic and english numbers

ar_en_numbers_convert.py

ar_numbers = "٠١٢٣٤٥٦٧٨٩"
en_numbers = "0123456789"

ar_number = "١٤٢٣٤٠٣٧osama"
en_number = "14234037osama"

def convert_numbers(text: str, to_language: str = "en") -> str:
    def _convertor(text: str, from_language: str, to_language: str) -> str:
        return "".join([to_language[from_language.index(n)] if n in from_language else n for n in text])

    if to_language == "en":
        return _convertor(text, ar_numbers, en_numbers)
    elif to_language == "ar":
        return _convertor(text, en_numbers, ar_numbers)
    else:
        raise ValueError("Invalid language")

print(convert_numbers(en_number, "ar"))
print(convert_numbers(ar_number, "en"))




## Using Enum
from enum import StrEnum


class Language(StrEnum):
    arabic = ar = "٠١٢٣٤٥٦٧٨٩"
    english = en = "0123456789"


def convert_numbers(text: str, from_language: Language, to_language: Language) -> str:
    return "".join(
        map(
            lambda n: to_language[from_language.value.index(n)] if n in from_language.value else n, 
            text
        )
    )

print(convert_numbers(en_number, Language.en, Language.ar))
print(convert_numbers(ar_number, Language.ar, Language.en))




## Using Built-in str method
def convert_numbers(text: str, to_language: str = "en") -> str:
    # Create translation tables for faster conversion
    ar_to_en = str.maketrans(ar_numbers, en_numbers)
    en_to_ar = str.maketrans(en_numbers, ar_numbers)

    if to_language not in ("en", "ar"):
        raise ValueError("Invalid language")
    return text.translate(ar_to_en if to_language == "en" else en_to_ar)

print(convert_numbers(en_number, "ar"))
print(convert_numbers(ar_number, "en"))
