How to delete all files in directory on remote SFTP server in Python?

You need a recursive routine since your remote directory may have subdirectories.

def rmtree(sftp, remotepath, level=0):
    for f in sftp.listdir_attr(remotepath):
        rpath = posixpath.join(remotepath, f.filename)
        if stat.S_ISDIR(f.st_mode):
            rmtree(sftp, rpath, level=(level + 1))
        else:
            rpath = posixpath.join(remotepath, f.filename)
            print('removing %s%s' % ('    ' * level, rpath))
            sftp.remove(rpath)
    print('removing %s%s' % ('    ' * level, remotepath))
    sftp.rmdir(remotepath)

ssh = paramiko.SSHClient()
ssh.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts")))
ssh.connect(server, username=username, pkey=mykey)
sftp = ssh.open_sftp()
rmtree(sftp, remoteArtifactPath)

# Close to end
stfp.close()
ssh.close()

I found a solution: Iterate over all the files in the remote location, then call remove on each of them:

ssh = paramiko.SSHClient()
ssh.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts")))
ssh.connect(server, username=username, pkey=mykey)
sftp = ssh.open_sftp()

# Updated code below:
filesInRemoteArtifacts = sftp.listdir(path=remoteArtifactPath)
for file in filesInRemoteArtifacts:
    sftp.remove(remoteArtifactPath+file)

# Close to end
sftp.close()
ssh.close()
