Script Python net_connect with Netmiko for router cisco error

Hello everyone I want to make a Python script with a menu and several possibilities but I have a problem. When I run my script everything works

I can type the information to connect but I have the right to the following errors:

Traceback (most recent call last):

File "test.py", line 38, in <module>show_int()File "test.py", line 24, in show_intoutput = net_connect.send_command("show ip int brief")AttributeError: 'NoneType' object has no attribute 'send_command'

Here is my script I have tried a lot of changes but I don't see where the problem is.

Thanks for your help
