Python 如何压缩以特定扩展名结尾的文件

我希望将所有文件放在一个以.npy或csv结尾的目录中(我是在执行了几次for循环之后才到达的--因此是四个.Path)，然后压缩这些文件. 我的代码正在运行，只将一个文件放在压缩文件中.我做错了什么？ 我try 更改缩进，但没有创建任何压缩文件

import json
import os
import zipfile
import zlib

directory = os.path.join(os.getcwd(), 'recs')
radarfolder = 'RadarIfxAvian'
file = os.listdir(directory)

def r(p, name):
    p = os.path.join(p, name)
    return p.replace("/", "\\") 

#This code will list all json files in e    ach file
for first in os.scandir(directory):
    if first.is_dir():
        for second in os.scandir(first.path):
            if second.is_dir():
               for third in os.scandir(second.path):
                if third.is_dir():
                    radar_folder_name = ''
                    list_files = ()
                    for fourth in os.scandir(third.path):
                        if fourth.is_dir():
                            if radarfolder in fourth.path:
                                radar_folder_name = fourth.path
                                print(radar_folder_name)
                                list_files = ()
                                for file in os.listdir(fourth.path):
                                    if file.endswith(".npy") | file.endswith(".csv"):
                                        list_files = (file)
                                        print(list_files)
                                    with zipfile.ZipFile(radar_folder_name +'\\' +'radar.zip', 'w', compression=zipfile.ZIP_DEFLATED ) as zipMe:
                                        zipMe.write(radar_folder_name +'\\' +list_files)            
                                        zipMe.close()

我try 更改缩进，要么导致错误:TypeError:只能将字符串(不是"tuple")连接为字符串，要么没有创建任何压缩文件
