在python中压缩文件 [英] Zipping files in python

问题描述

我的程序运行顺利，但我希望将 ftp 中的文件压缩到本地驱动器中

My Program runs smoothly but I want my files from ftp to be zip in my local drive

我的问题:调用我的 main() 函数后只有 1 个文件被压缩

My Problem : Only 1 file is being zipped after calling my main() function

这是我的代码:

import os
import upload
import download
import zipfile
import ConfigParser
import ftputil

def main():
    
    #create a folder Temp on d drive for later use
    path = r'D:\Temp'
    os.mkdir(path)
    
    #parse all the  values at config.ini file
    config = ConfigParser.ConfigParser()
    config.readfp(open('config.ini'))
    server = config.get('main', 'Server')
    username = config.get('main', 'Username')
    password = config.get('main', 'Password')
    uploads = config.get('main', 'Upload folder')
    downloads = config.get('main', 'Download folder')

    #connect to ftp
    ftp = ftputil.FTPHost(server, username, password)

    dirlist = ftp.listdir(downloads)
    
    for list in dirlist:
        ftp.chdir(downloads)
        target = os.path.join(path, list)
        ftp.download(list, target)

    #zipping files
    absolute_path = r'D:\Temp'
    dirlist = os.listdir(absolute_path)
    filepath = r'D:\Temp\project2.zip'
    for list in dirlist:
        get_file = os.path.join(absolute_path, list)
        zip_name = zipfile.ZipFile(filepath, 'w')
        zip_name.write(get_file, 'Project2b\\' + list)
        
                
        

if __name__ == '__main__':
    print "cannot be"

推荐答案

当你这样做时:

for list in dirlist:
        get_file = os.path.join(absolute_path, list)
        zip_name = zipfile.ZipFile(filepath, 'w')
        zip_name.write(get_file, 'Project2b\\' + list)

您为每个要压缩的文件重新创建一个 ZipFile，"w" 模式意味着您从头开始重新创建它.

you recreate a ZipFile for each file you want to zip, the "w" mode means you recreate it from scratch.

试试这个(在循环之前创建 zip 文件):

Try this (create the zip file before the loop) :

zip_name = zipfile.ZipFile(filepath, 'w')
for list in dirlist:
        get_file = os.path.join(absolute_path, list)
        zip_name.write(get_file, 'Project2b\\' + list)

或者这样，它将以追加模式打开压缩文件:

Or this, it will open the zipfile in append mode:

for list in dirlist:
        get_file = os.path.join(absolute_path, list)
        zip_name = zipfile.ZipFile(filepath, 'a')
        zip_name.write(get_file, 'Project2b\\' + list)
