Python,paramiko,invoke_shell和丑陋的字符

Question

当我运行以下Python代码时:

import workflow
import console
import paramiko
import time

strComputer = 'server.com'
strUser = 'user'
strPwd = 'passwd'

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname=strComputer, username=strUser, password=strPwd)

channel = client.invoke_shell()
channel.send('ls\n')
time.sleep(3)
output=channel.recv(2024)
print(output)

#Close the connection
client.close()
print('Connection closed.')

我得到了与丑陋字符混合的所需输出:

任何人都可以解释我发生了什么,以及如何获得一个漂亮的输出？谢谢

这些是用于ls突出显示目录,可执行文件等的终端颜色代码,您可以显式调用/bin/ls(或在某些发行版上ls --color=never)以避免调用别名等并获得无色输出.

使用那些神秘的代码来定义颜色[0m[01;34m.这ls是启用着色时终端的样子:
