Hi,
You just missed the commas in the scripts config_commands. Please modify it as below and test again:
config_commands = [ 'int loop 1',
'ip add 1.1.1.1 255.255.255.0',
'return',
'save',]

after add commas

Well, when you type the save on the device, it will require you to enter Y or N to confirm the operating. I'm not sure if the netmiko supports pause a second after executing some command and then send other commands to the device. If yes, you can try adding extra config_commands below after pause the program for about one second.
config_commands = [ 'y',]

If not, please try to modify the config_commands as below:
config_commands = [ 'int loop 1',
'ip add 1.1.1.1 255.255.255.0',
'return',
'save',
'y',]

config_commands = [ 'y',]

No, the command 'y' should be typed after the command 'save'. I'm not sure whether a comma should be followed 'save'. Maybe, you can refer to the output of the device as below:
