使用python实现字典格式的文件利用key取value并写入txt或者csv文件

import json
items=  {"totalPages":33,"numberOfElements":20,"totalElements":647,"content":[{"id":1,"schoolName":"北京大学","schoolCode":"10001","schoolIdentificationCode":"4111010001","department":"教育部","provinces":"北京","city":"北京市","educationLevel":"本科","isPrivateSchool":"","isDoubleTop":"双一流","isNineEightFive":"985","isTwoOneOne":"211","isOneZeroZero":"","wslCountry":"2","wslProvinces":"2","xyhCountry":"1","xyhCrovinces":"1","schoolUrl":"http://www.gotopku.cn/"},{"id":2,"schoolName":"中国人民大学","schoolCode":"10002","schoolIdentificationCode":"4111010002","department":"教育部","provinces":"北京","city":"北京市","educationLevel":"本科","isPrivateSchool":"","isDoubleTop":"双一流","isNineEightFive":"985","isTwoOneOne":"211","isOneZeroZero":"","wslCountry":"21","wslProvinces":"3","xyhCountry":"8","xyhCrovinces":"3","schoolUrl":"http://rdzs.ruc.edu.cn/"},{"id":18,"schoolName":"中国农业大学","schoolCode":"10019","schoolIdentificationCode":"4111010019","department":"教育部","provinces":"北京","city":"北京市","educationLevel":"本科","isPrivateSchool":"","isDoubleTop":"双一流","isNineEightFive":"985","isTwoOneOne":"211","isOneZeroZero":"","wslCountry":"35","wslProvinces":"7","xyhCountry":"33","xyhCrovinces":"6","schoolUrl":"http://jwzs.cau.edu.cn/"}],"number":1}
# print(type(items))
item=json.dumps(items) # 转为json格式
jsons=json.loads(item) # json格式解析
# print(jsons)
ss=jsons['content']
# print(ss)
for s in ss: #字典遍历取值
    # print(s['schoolName'])

    #  没有指定任何文件格式，也能写入成功，然后可以右击文件，选择打开文件的方式
    with open ('our_school',"a+",encoding="utf-8") as f:
        f.write(s['schoolName']+'\r\n')
    #  写入txt文件

    with open ('our_school.txt',"a+",encoding="utf-8") as f:
        f.write(s['schoolName']+'\r\n')
    #  写入csv文件
    with open ('our_school.csv',"a+",newline='',encoding="utf-8-sig") as f: # 注意此处写encoding="utf-8"会出现乱码;此外，使用newline=''避免出现空行
        f.write(s['schoolName']+'\r\n')

# 最终结果--------------------------------------------------------------------
