Python中使用glob和rmtree删除目录子目录及所有文件的例子
一、batch与shell中
目录及文件:
C:\TESTFOLDER\TEST
├─Test2
└─Test3
test.txt
删除目录及其下的所有文件:
rmdir /S /Q c:\TestFolder\test
删除所有目录下的文件,但是目录结构不能被删除:
del /F /S /Q c:\TestFolder\test\*
Linux类似的命令为:
rm /rf /home/aaa/test
二、python中
:注意如果有错误会有异常抛出,需要处理异常。
1)删除文件且不支持通配符: os.remove()
2) 删除空的目录: os.rmdir()
3) 删除空的目录及子目录: os.removedirs()
3) 删除目录及其子目录中的文件:shutil.rmtree()
rmtree+异常处理:
#code:
import shutil
def retreeExceptionHandler(fun,path,excinfo):
print("Error:" + path)
print(excinfo[1])
shutil.rmtree('c:\\testfolder\\test',ignore_errors=False,onerror=retreeExceptionHandler)
#result:
Error:c:\testfolder\test\Test3
[Error 32] The process cannot access the file because it is being used by another process: 'c:\\testfolder\\test\\Test3'
Error:c:\testfolder\test
[Error 145] The directory is not empty: 'c:\\testfolder\\test'
使用rmdir和remove等价于rmtree:

rmgeneric(fullpath, f)

三、通配符
