TypeError: can only concatenate list (not "int") to list

I am getting the below error while executing the below commands: a=[1,2,3] b=a+3;

TypeError: can only concatenate list (not "int") to list

Commands executed: Conda Base Environment (base) [root@ip-****** ec2-user]# octave-cli bash: octave-cli: command not found

Conda Octave Environment [where octave and octave_kernel is installed]

Looks like Jupyter notebook kernel is unable to use octave. Could you please through some tips to resolve this issue ?

@dsblank : Yes I am using octave kernel.
