.Desktop problems

[mepyyeti]

Regarding RUNNING a .py through a desktop icon. .Desktop is the Linux version of an .exe . I wasn't able to find a solution to this (tried stackexchange and FreeDesktop.org). So hopefully other users benefit from this. I couldn't find a similar issue so maybe this is helpful.

I have a working .py and want to put it on the desktop w/ its own icon and be able to run it by clicking the icon. I set up the .desktop file

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=SomeApp
Comment=SimiApp
Exec=/usr/share/applications/simi0op.py
Icon=/usr/share/icons/hicolor/48x48/apps/gw48.png
Terminal=true

Exec/Icon all are placed **correctly** Meaning simi0op.py is in the directory Exec points to. Same thing for my icon file, gw48.png.

me@me-ubuntu:~$ cd /
me@me-ubuntu:/$ sudo -i
[sudo] password for me:
root@me-ubuntu:~# mv /home/me/Documents/py/cs/test0.desktop /usr/share/applications/
root@me-ubuntu:~# cp /usr/share/applications/test0.desktop /home/me/Desktop
root@me-ubuntu:~# exit
logout

There is a generic icon on the desktop now w/ tiny lock on it. Double clicking the icon prompts 'untrusted to launch'.

I ran ls -lsh on my desktop

closest thing I found regard 'untrusted to launch' in Ubuntu 17.10 is here:launchpad untrusted to launch bug in 17.10
However this bug has been fixed

So, the problem:
1) File will not run 'there was an error launching the application'. PLEASE HELP

Where did I go wrong? I can ls into the directories and the files **ARE** there....very frustrated....
