problem with python program

[Raymondo02]

Hello,
I installed the last version of rasbian on my Raspberry pi 3 B+. I check in the programming section and the Python IDLE is not there. I need this to continu my project. So how can I have it back?

Have you tried Thonny, much better than IDLE.

Probably part of consistent moves by Raspberry Pi to wean you off the Python2 dialect of the language which reaches End of Life at the end of this year.

The menu item was removed in a release of Raspbian 12 months ago.

In the June 2019 release the IDLE IDE itself has been removed.

I believe the underlying Python2 interpreter is still installed by default, so your ability to develop and run python code is unaffected.

So to continue to use the Python2 version of IDLE you will need to reinstall the program itself as well as reinstating the menu item.

Maybe simpler to just make the move to Python3? And you might find that the Thonny Python editor is nicer to use. (The Mu python editor is also worth investigating, but is not a default Installation in Raspbian yet.)

Thank you, I try Thonny and I like it.

But I have another problem. In my program, I use GPIO. So, I write at the beginning : import RPi.GPIO as GPIO. When I run it, I receive ModuleNotFoundError : No module named 'RPi'.

I already download the GPIO module. So, how I fix that ?

Do you have both python-rpi-gpio and python3-rpi-gpio installed.

It really would be better if you ditched python2 and stuck to python3.

Thonny won't work with large python scripts.

You can install idle and use it. sudo apt install idle

Have you reported that as an issue?

Reported it now. Loading my script of 5900 lines takes 4 minutes 50 seconds !!. IDLE or Geany take about 1 second.
I don't mind if its meant for beginners with small scripts, BUT don't take IDLE off the standard build in favour of Thonny.

I got a reply.. It wasn't intended for large python scripts but should improve...

Great to see they are looking into your issue and finding improvements.

I have to ask why have you not broken your code into smaller files?

[gordon77]

Because previously it wasn't a problem.
