HP prime Python code Python app

[Grigosvili]

Hello everyone,

I am new to the forum and to the HP Prime, so I am sorry for my lack of knowledge on both of them. Now, I bought my HP prime few months ago, and I saw it had a Python support, so I tried to run a Python code I wrote on my computer and after some time of making the code more simple etc. I managed to make it work on my HP prime. I would enter the CAS mode and call my program with a () on the end and it showed me all the dialogue windows I wanted and calculated everything I wanted. However, yesterday I updated it and on the connectivity kit it now shows that it is Beta version and the calculator now has new app, Python, and my program would no longer work in the CAS mode, it would just reboot the calculator when i tried to run it, like before. Now I saw few posts on how to run a python code, but with me being new to calculator, I didn't find them helpfull.
I was wondering if someone, who doesn't mind explaining this to me, a newbie, could tell me how to run a Python code, previously wrote on my pc in the python app. I understood there were numeric view, which is a shell, and a symbolic view, in which I can write the program on a calculator itself, but I don't see any save options, and I don't know how to run the program wrote in Symb in a Num view. An actual example would probably be the best.
Once again, please remeber I am new to HP graphic calculator,

Best regards
