python ftplib写一个判断远端路径是文件还是文件夹

import ftplib
from ftplib import FTP
ftp = FTP("192.168.0.112")
ftp.login(user=username, passwd=password)


def ftp_remote_path_is_directory(ftp, remote_path):
	current_path = ftp.pwd()
	try:
		ftp.cwd(remote_path)
	except ftplib.error_perm as e:
		if str(e).startwith("550"):
			return False
		else:
			print(f"other error check error code{str(e)}")
			return None
	ftp.cwd(current_path)
	return True


def ftp_remote_path_is_file(ftp, remote_path):
	current_path = ftp.pwd()
	try:
		ftp.cwd(remote_path)
	except ftplib.error_perm as e:
		if str(e).startwith("550"):
			return True
		else:
			print(f"other error check error code{str(e)}")
			return None
	ftp.cwd(current_path)
	return False
