How can I send multiple commands to a remote server using Python

Question

How can I send multiple commands to a remote server using Python? I had to learn Python for study purposes, I decided to try to automate the collection of information from the Bacula consoles. I'm trying with the following script, but I'm not having success. Could you show me where I went wrong?

HOST= 'server.name.com.br'

try:
    s = pxssh.pxssh()
    hostname = HOST 
    username = 'root'
    password = 'xxxxxxx' 
    s.login(hostname, username, password)
    s.sendline('bconsole')   # run a command
    s.prompt()               # match the prompt
    print(s.before)          # print everything before the prompt.
    s.prompt()               # match the prompt
    s.sendline('st')   # run a command
    s.prompt()               # match the prompt
    print(s.before)          # print everything before the prompt.
    s.prompt()               # match the prompt
    s.sendline('1')   # run a command
    s.prompt()               # match the prompt
    print(s.before)          # print everything before the prompt.
    s.prompt()               # match the prompt

    s.logout()
except pxssh.ExceptionPxssh as e:
    print("pxssh failed on login.")

Output:
