How to execute multiple CLI commands in a python script?

I am using TeamForge's CLI to create artifacts in the Defects tracker section. The CLI file/executable is called "ctf" with no extensions. I want to use a python script to create artifacts but can only execute one command at most. I want to create a bug in one shot. This is the code I have so far:

import os
os.system("./ctf    go tracker1234;             # going to Defects section
                    create;                     # creating an artifact
                    set title This Is A Title;  # setting artifact's fields
                    set description desc123; 
                    set Product [Product 23]; 
                    set build_number Not known; 
                    set Severity Catastrophic; 
                    set steps_to_reproduce 1st comment; 
                    set Component [component 4]; 
                    set Version [version 19]; 
                    commit)                     # saving the artifact on TeamForge

Here is the error I keep getting:

sh: 1: create: not found
sh: 1: commit: not found

So I believe that these commands are not being executed sequentially or in the order that I have specified. This means that each command is being executed separately. Any suggestions to get these commands running in the order that I have specified?

Let me know if further explanation is required.

Update

I just found out that you can do this: go tracker1234 create which is two steps in one

You could try to quote your arguments to ctf; just look at this:

>>> os.system("echo hi; echo again;")
hi
again

versus:

>>> os.system("echo 'hi; echo again;'")
hi; echo again;

The semicolon terminates a command in a shell. If your arguments contain semicolons, you must quote them so they don't break your list of arguments.

However, according to the CTF guidelines, their way of handling such a situation with multiple commands seems to be putting them into a script and executing that with:

./ctf script.txt
