Python 将省、市 json 替换 成拼音

import pypinyin
import re
def pinyin(word):
 s = ''
for i in pypinyin.pinyin(word, style=pypinyin.NORMAL):
    s += ''.join(i)
return s
def run(): 
    fname = 'city_code_cn.json'    #文件夹路径
    fs = open('city_code_en.json','w') #每次重新写入
    with open(fname,'r',encoding='utf-8') as f:         
         for line in f.readlines(): 
            pattern = r'[\u4e00-\u9fa5]+' #汉字正则
            c =re.compile(pattern) #找出汉字
            py=pinyin(c.findall(line)).title() # 将汉字转换成拼音,并将首字母大写
            result= re.sub(pattern,py,line) #将每一行中的汉字替换成拼音
            fs.write(result) #写入文件
            print(result)
    fs.close()
