python压缩文件、复制文件

python常用程序

---

1、压缩文件

import zipfile
import os
def zipDir(dirpath,outFullName):
    """
    压缩指定文件夹
    :param dirpath: 目标文件夹路径
    :param outFullName: 压缩文件保存路径+xxxx.zip
    :return: 无
    """
    zip = zipfile.ZipFile(outFullName,"w",zipfile.ZIP_DEFLATED)
    for path,dirnames,filenames in os.walk(dirpath):
        # 去掉目标跟路径，只对目标文件夹下边的文件及文件夹进行压缩
        fpath = path.replace(dirpath,'')
 
        for filename in filenames:
            zip.write(os.path.join(path,filename),os.path.join(fpath,filename))
    zip.close()
zipDir("/home/aistudio/exp_1/out","/home/aistudio/submission.zip")

2、复制文件

一个文件夹内的文件复制到另一个文件夹。

src_path源文件夹， target_path目标文件

import os
 
def copy_dir(src_path, target_path):
	if os.path.isdir(src_path) and os.path.isdir(target_path):		
		filelist_src = os.listdir(src_path)							
		for file in filelist_src:
			path = os.path.join(os.path.abspath(src_path), file)	
			if os.path.isdir(path):
				path1 = os.path.join(os.path.abspath(target_path), file)	
				if not os.path.exists(path1):						
					os.mkdir(path1)
				copy_dir(path,path1)			
			else:								
				with open(path, 'rb') as read_stream:
					contents = read_stream.read()
					path1 = os.path.join(target_path, file)
					with open(path1, 'wb') as write_stream:
						write_stream.write(contents)
		return 	True	
						
	else:
		return False	
copy_dir('exp_1/out', 'work/train/label')
