Python Launch Options

[Flexico]

I'm not sure if this is more a Python question or a Linux question, but here goes: I have a script file tied to the key combo Ctrl+Alt+P to navigate to my script folder and run Python. That part works.

#!/bin/bash
mate-terminal --working-directory="/home/flexico/Documents/Python_Scripts" --title="Python" --command python

However, I also want it to run a few lines of Python script, like import some standard libraries so I don't have to re-type them in every time. How do I do that? I tried adjusting the program like so:

#!/bin/bash
mate-terminal --working-directory="/home/flexico/Documents/Python_Scripts" --title="Python" --command "python /home/flexico/python_start.py"

But it just opens a blank Terminal window with a flashing cursor, which disappears when I click on it.
