如何使用可执行的Linux程序/脚本更改python文件中的变量？

Question

I am building a datalogger for a group of PV inverters using Raspberry Pi and am using two python scripts to collect the data over two separate communication protocols. I need to change two variables in each script if I move from one site to another - the first and the last inverter id for the new site. I want to make this change user friendly such that a new user does not have to open the python script to change the values. So I want to have an executable program in linux environment (which may have an icon on the Pi desktop) which the user can open and it will prompt to specify first and last inverter id and transfers this change to python script. If this is too complicated to achieve for this task, maybe a simple command for the terminal window which will prompt the same changes??

I hope the task is sufficiently explained. I am not a programmer by trade and am doing this project as a hobby, so please forgive me if I am ignoring something obvious :|

Just posting a successful update for this query. The desktop configuration file method was the simplest and it worked. I wrote the following in the .desktop file

[Desktop Entry]
Version=1.0
Name= ProgramName
Comment= my comment
Exec=sudo python /usr/share/app/app.py
Icon=/usr/share/pixmaps/geany.xpm
Path=/usr/local/lib/python2.7
Terminal=true
Type=Application
Categories=Utility;Application;

I added the "python" bit to the Exec line and hence did not have to write a she-bang line in the script. Also the Terminal option had to made True since I needed a prompt for the user to enter a value.

Hope this helps somebody else.
