The fastest way to execute a Python script is to not open any windows:
1) Write the Python script either on the UQAM servers with 'vi' or 'vim', or, if you are not comfortable with these, you can also write the script on your local computer and copy it on the servers to execute it there.
2) Acquire a Python version - see below "Accéder à Python"
3) Execute Python script with
python scriptname
