最近项目需要使用多国语言版本，但是项目之前的代码使用了Layui组件，全网找不到layui的多语言，只能自己动手做，使用Python脚本提取组件中所有的中文。

       1、到官网下载完整的版本，一定不要用压缩包，改了容易报错

       2、Python遍历文件夹

import io
import os
import re
import hashlib


filepath = "\\layui\\layui-zh-CN\\modules" 

# 遍历指定目录，显示目录下的所有文件名
def each_file(filepath):
    chinese_charsList = []
    languagefile = "language.txt"
    for root, dirs, files in os.walk(filepath):
        for file in files:
            if(file.find(languagefile)== -1):#过滤语言包，避免重复运行一直累加
                filename = os.path.join(root, file)
                print(filename+"\n")

                filtered_chinese_chars = read_file(filename)
                chinese_charsList = chinese_charsList + filtered_chinese_chars

    #chinese_charsList = list(set(chinese_charsList))
    # 构建新的文件路径，将后缀改为.txt
    new_file_path = os.path.join(filepath, languagefile)
    if(len(chinese_charsList)>0):
        with open(new_file_path, 'w', encoding='utf-8') as file:
            file.write("\n".join(chinese_charsList))

        3、提取中文字符，并保存到language.txt，保存格式为KeyValue模式，方便替换的时候查找

def read_file(filename):
    #if(filename.find('carousel.js')!= -1):
        chinese_pattern = re.compile('[\u4e00-\u9fff]+')
        filtered_chinese_chars = []
        with open(filename, 'r', encoding='utf-8') as file:
            for line in file:
                matches = chinese_pattern.findall(line)
                for match in matches:
                    #过滤js文件里面 // 和*开头的行
                    if (not line.strip().startswith('//')) and (not line.strip().startswith('*')): 
                        #查找字符串面是否直接带// /*
                        index_target = line.find(match)
                        if index_target > 0:
                            preceding_text = line[:index_target]
                            if ("//" not in preceding_text) and ("/*" not in preceding_text):
                                #增加字符串的Md5标识，方便之后翻译后替换
                                md5 = hashlib.md5(match.encode('utf-8')).hexdigest()
                                file_name = os.path.basename(filename)
                                #保存格式文件名，字符串M5,需要翻译的汉字
                                filtered_chinese_chars.append(file_name+"_"+md5+"="+match)
                                #print(match)

        
        return filtered_chinese_chars

        4、运行主程序

if __name__ == '__main__':
  each_file(filepath)
