Python 3.2 实现zip压缩与解压缩功能

功能有限,要按照脚本压缩文件或者文件夹,必须进入文件所在目录,以文件所在目录为工作路径,并且默认压缩后的文件名同于原文件所在的目录名、解压后的文件夹名同于解压前的文件名
压缩功能分为压缩所在目录的所有文件跟部分文件(部分文件需要手动添加文件名);解压功能分为解压到当前目录跟解压到指定目录,以下为代码:
- #!/usr/bin/env python3
- import os,zipfile
- def Zip(target_dir):
- target_file=os.path.basename(os.getcwd())+‘.zip’
- zip_opt=input(“Will you zip all the files in this dir?(Choose ‘n’ you should add files by hand)y/n: “)
- while True:
- if zip_opt==‘y’: #compress all the files in this dir
- filenames=os.listdir(os.getcwd()) #get the file-list of this dir
- zipfiles=zipfile.ZipFile(os.path.join(target_dir,target_file),‘w’,compression=zipfile.ZIP_DEFLATED)
- for files in filenames:
- zipfiles.write(files)
- zipfiles.close()
- print(“Zip finished!”)
- break
- elif zip_opt==‘n’: #compress part of files of this dir
- filenames=list(input(“Please input the files’ name you wanna zip:”))
- zipfiles=zipfile.ZipFile(os.path.join(target_dir,target_file),‘w’,compression=zipfile.ZIP_DEFLATED)
- for files in filenames:
- zipfiles.write(files)
- zipfiles.close()
- print(“Zip finished!”)
- break
- else:
- print(“Please in put the character ‘y’ or ‘n'”)
- zip_opt=input(“Will you zip all the files in this dir?(Choose ‘n’ you should add files by hand)y/n: “)
- def Unzip(target_dir):
- target_name=input(“Please input the file you wanna unzip:”)
- zipfiles=zipfile.ZipFile(target_name,‘r’)
- zipfiles.extractall(os.path.join(target_dir,os.path.splitext(target_name)[0]))
- zipfiles.close()
- print(“Unzip finished!”)
- def main():
- opt=input(“What are you gonna do?Zip choose ‘y’,unzip choose ‘n’.y/n: “)
- while True:
- if opt==‘y’: #compress files
- zip_dir=input(“Please input the absdir you wanna put the zip file in:”)
- Zip(zip_dir)
- break
- elif opt==‘n’: #unzip files
- unzip_dir=input(“Please input the absdir you wanna put the zip file in(Nothing should be done if you wann unzip files in the current dir):”)
- if unzip_dir==”:
- Unzip(os.getcwd())
- else:
- Unzip(unzip_dir)
- break
- else:
- print(“Please input the character ‘y’ or ‘n'”)
- opt=input(“What are you gonna do?Zip choose ‘y’,unzip choose ‘n’.y/n: “)
