Thonny - A Python IDE for Beginners

I received an email a few days back from Aivar Annamaa about a Python IDE for beginners called Thonny.

The YouTube video introducing the IDE looks promising, so I am jumping at the opportunity to take a look at it.

Thonny is in the Python Package Index, so it can be easily installed (and installed by user without system admin privileges) using pip.  In a previous post I documented installing Python 3.4, which is required to before what follows.

First I want to get pip3.  Since it is not yet in the main Centos repository, I installed it with (note: run $ sudo -i and then # exit before running this command in the same terminal emulator so as not to be prompted for a sudo password):
$ curl https://bootstrap.pypa.io/get-pip.py | sudo python3.4
I want to install Thonny inside the user's local directory, so I installed it with:
$ pip3 install --user thonny
This installs the thonny egg in $HOME/.local/lib/python3.4/site-packages (creating the needed lib/python3.4/site-package directory if it is not already there), and installs a shell script to launch it in $HOME/.local/bin. When I tried running thonny from the command prompt, I got an error message: ImportError: No module named 'tkinter'. So I needed to install tkinter:
$ sudo yum install python34-tkinter
after which thonny launched.  It complained that it couldn't find rope or jedi, however, so I installed those locally as well:
$ pip3 install --user rope
$ pip3 install --user jedi
Since thonny is a GUI IDE, I wanted a GUI launcher for it.  To get one I created a Thonny.desktop file based on the one I found here, with the following contents:
[Desktop Entry]
Type=Application
Name=Thonny
GenericName=Python IDE
Exec=/home/[username]/.local/bin/thonny %F
Comment=Python IDE for beginners
Icon=/home/[username]/.local/lib/python3.4/site-packages/thonny/res/thonny.ico
Terminal=false
Categories=Application;Education;Development;Debugger;IDE;
MimeType=text/x-python;
Actions=Edit;

[Desktop Action Edit]
Exec=/home/[username]/.local/bin/thonny %F
Name=Edit with Thonny
and placed it in my /home/[username]/.local/applications directory (Note: replace [username] with your actual username).

Here is a screenshot of Thonny running hello.py:
My next task will be to go through some beginner Python lessons using Thonny to see how it feels.

  2. If this is an IDE for beginners, why are the instructions to install Thonny not for beginners? I have no clue how to install Thonny the way you describe.

  3. There are easy to use installers as well (at least they are easy for Windows and MacOS), with links off the Thonny home page:

  4. Newer versions of python come with pip installed and setup with environment variables out of the box. I installed thonny using pip from the command prompt in Windows 10 with python 3.6

  10. I am also new to Python.
    In the past I have been put off by the (to me) arcane command line entries needed to set everything up.
    But I went to the Thonny website downloaded the windows package and it, I could start programming with the minimum of fuss.
    Excellent.. Thank you!!!
