number_to_words() convert and replace all numbers in a sentence instead of giving back only converted numbers

I came across this library but in the documentation there was no convert numbers to words + change them in a sentence. so i made a function for that.

sentence = extract_replace("In 2019, mark saved $15 thousand, for a total savings of 54 thousand over eight years." ) print(sentence)

output : In two thousand and nineteen, mark saved $fifteen thousand, for a total savings of fifty-four thousand over eight years.

i made the extract_replace() function which calls another function that i made called find_num_index() .

i would appreciate if anyone can tell me if i can commit my work to help other people who might need this function to directly convert numbers to words in sentences in the future.

Thank you :)
