文字数字转整数：Python现有可用库咨询（支持0至百万）

Hey there! Awesome call looking for existing libraries instead of building a parser from scratch—Python's got you covered here, with solid tools that handle both English and Spanish written numbers right up to the million range you need.

Here are the go-to options:

1. 英文文字转数字：word2number #

This is the most widely used library for English, and it handles numbers well beyond a million with ease. It takes care of spaces, hyphens, and common phrasing like "twenty two" or "one hundred and fifty".

• Install it via pip:

  pip install word2number
  

• Example usage:

  from word2number import w2n
  
  # Convert English text to integer
  print(w2n.word_to_num('twenty two'))  # Output: 22
  print(w2n.word_to_num('one million'))  # Output: 1000000
  print(w2n.word_to_num('nine hundred ninety nine thousand nine hundred ninety nine'))  # Output: 999999
  

2. 西班牙语文字转数字：spanish_word2num #

For Spanish, this dedicated library is perfect—it supports all standard number phrasing (including regional variants like "un millón" vs "un millon" if needed) and covers your 0 to 1,000,000 range flawlessly.

• Install it via pip:

  pip install spanish-word2num
  

• Example usage:

  from spanish_word2num import spanish_to_num
  
  # Convert Spanish text to integer
  print(spanish_to_num('veintidós'))  # Output: 22
  print(spanish_to_num('un millón'))  # Output: 1000000
  print(spanish_to_num('doscientos treinta y cuatro mil quinientos sesenta y siete'))  # Output: 234567
  

Bonus: Dual-language wrapper #

If you need to handle both languages in one function, you can throw together a simple wrapper to switch between the two libraries:

from word2number import w2n
from spanish_word2num import spanish_to_num

def text_to_num(text, language='english'):
    if language.lower() == 'english':
        return w2n.word_to_num(text)
    elif language.lower() == 'spanish':
        return spanish_to_num(text)
    else:
        raise ValueError("Unsupported language. Choose 'english' or 'spanish'.")

# Test it out
print(text_to_num('twenty two', 'english'))  # 22
print(text_to_num('veintidós', 'spanish'))  # 22

All these libraries handle the grammar rules and edge cases (like hyphenated numbers, compound phrases) out of the box, so you don't have to mess with writing a custom parser or formal grammar.
