前今天没事写了个解压文件的api.

import zipfile
import os
class ZipfileApi(object):
    def compressionFile(self,filepath,zipname,format):
        if  not  os.path.isdir(filepath):
            zipName=zipname+"."+format
            zipName=zipName.decode("utf-8")
            filepath=filepath.decode("utf-8")
            root,file=os.path.split(filepath)
            #os.chdir(rootname)
            f = zipfile.ZipFile(zipName, 'w', zipfile.ZIP_DEFLATED)
            f.write(file)
            f.close()
        else:
            zipName=zipname+"."+format
            zipName=zipName.decode("utf-8")
            filepath=filepath.decode("utf-8")
            f = zipfile.ZipFile(zipName, 'w', zipfile.ZIP_DEFLATED)
            current=os.path.abspath(os.path.join(filepath,".."))
            os.chdir(current)
            filepath=filepath.replace("\\",'/')
            currentRoot=filepath.split("/")[-1]
            print currentRoot
            for root, dirs, files in os.walk(currentRoot):
                for file in files:
                    f.write(os.path.join(root,file))
            f.close()
    def unpackFile(self,filepath,savepath=''):
        filepath=filepath.decode("utf-8")
        savepath=savepath.decode("utf-8")
        f = zipfile.ZipFile(filepath,'r')
        for file in f.namelist():
            f.extract(file,savepath)


zip1=ZipfileApi()
zip1.compressionFile(r"C:\Users\Administrator\Desktop\root\qwert",r"D:/root","rar")
#zip1.unpackFile(r"D:\root.rar",r"C:\Users\Administrator\Desktop")

1，首先，ZipfileApi()实例化；
2，compressionFile，传递压缩路径（文件或目录），压缩文件名，压缩格式等
3，unpackFile，解压文件名，解压路径

再附上一个可以再txt里寻找密码的小案例。

#coding:utf-8
# zip文件
import zipfile
import os
# 对zip文件进行密码测试，成功返回True，失败返回False
def testZip(filePathname,password):
    # 判断目录是否存在
    #filePathname=filePathname.decode("utf-8")

    if os.path.exists(filePathname)==False:
        print("文件"+filePathname+"不存在")
        return False
    #print filePathname
    zfile=zipfile.ZipFile(filePathname,"r")



    try:
        zfile.extractall(pwd=password.encode('utf-8'))
        return True
    except Exception as e:
        #print(e)
        return False


# 入口函数
def main():
    passFile=open(r'C:\Users\Administrator\Desktop\mayaApi\pass.txt')

    for line in passFile.readlines():
        password=line.strip()
        pw=password
        #print password
        if testZip(r'C:\Users\Administrator\Desktop\mayaApi\pass.zip',pw)==True:
            passFile.close()
            passFile=open(r'C:\Users\Administrator\Desktop\mayaApi\pass.txt','a+')
            print pw
            passFile.write('\n'+pw)



            passFile.close()




# Kickoff Start
main()
