python - paramiko怎么判断远程目录是否存在？

Question

如题：paramiko怎么判断远程目录是否存在？在调用exec_command函数的时候，怎么判断远程目录是否存在呢？ 因为这里不能传if进去。

怪我咯 · Answer

You can use a simpler method, run some commands to detect the directory, such as ls, and then check the output!

stdin,stdout,stderr = client.exec_command('ls DIR')
if stdout.readline() != '':
    print("exist")
else:
    print("not exist")

Method 2:
Use sftp, do not use exec_command

sftp = client.open_sftp()
try:
    sftp.stat(path)
    print("exist")
except IOError:
    print("not exist")
