Function net_connect.send_command, rstrip error

[wmann]

As the HP Procurve switches could run show commands in config mode. There was no problem using net_connect.send_config_set command for show commands. This works fine.

Code looks like this:
SSHClass = netmiko.ssh_dispatcher(device_type=switch['device_type'])
net_connect = SSHClass(**switch)
show_commands = ['show run']
output = net_connect.send_config_set(show_commands, delay_factor=2)

This works fine. Now I want to use the send_command function. I replaced send_config_set with send_command so the code looks like this

SSHClass = netmiko.ssh_dispatcher(device_type=switch['device_type'])
net_connect = SSHClass(**switch)
show_commands = ['show run']
output = net_connect.send_command(show_commands, delay_factor=2)

With this function I get the following error:

Traceback (most recent call last):
File "script.py", line 33, in
output = net_connect.send_command(show_commands, delay_factor=2)
File "C:\Python27\lib\site-packages\netmiko\base_connection.py", line 355, in send_command
command_string = command_string.rstrip("\n")
AttributeError: 'list' object has no attribute 'rstrip'

Any idea how to fix this?

@wmann
show_commands needs to be a string and not a list.

So change this:
show_commands = ['show run']

To this:
show_commands = 'show run'

[wmann]

I should learn more python ;-(

But this
show_commands = ['show system', 'show interfaces transceiver']
seems to work. So if there is only one command only a string. When multiple then a list?

[wmann]

Damn, it might be to late for coding today.
Haven't changed the function in the second command. So how can I use a string and use multiple show commands?

@wmann

Just use a for loop and gather the output.

show_commands = ['show system', 'show interfaces transceiver']
output = ''
for cmd in show_commands:
     output += net_connect.send_command(cmd, delay_factor=2)

Each time through the loop 'cmd' will be set to one of the commands.
output will have the results of the multiple commands
