To remove an entry from the alternatives table, simply type something like this (we will remove the table entry for Python 3.5 in this example): sudo update-alternatives -remove python /usr/bin/python3.5Īlways read more Python related topics on our main Python page. D: Click on the floppy disk icon to save the code. C: If your Raspberry Pi Pico is already plugged into your computer, you can open files that already exist on your computer or Pico. B: This paper icon allows you to create a new file. One day, your Python version(s) will change. A: The menu bar containing New, Save, Edit, View, Run, Debug, etc. Just invoke the command below and make your choice.
If you have followed the guide above, you can from now on switch preferred Python versions anytime. Similarly to above, you can also list the priorities table to confirm: update-alternatives -list python You should see Python 3 as preferred version (due to the priority setting in the priorities table)
#Thonny python 2.7 manual#
That means, if no manual alternative selection is made the alternative with the highest priority number will be set. thonny-4.0.1.bash is a script, which downloads and installs thonny-4.0. (with Python 3.10) when run on x8664 machines. The -install option take multiple arguments from which it will be able to create a symbolic link. If successful, you will end up with output similar to this. Sudo update-alternatives -install /usr/bin/python python /usr/bin/python3.5 2 Sudo update-alternatives -install /usr/bin/python python /usr/bin/python2.7 1 Notice we use only the first 2 digits of the version (i.e. Make sure to substitute the versions of Python in the command below with the versions of your system, which you have noted in the first step.
#Thonny python 2.7 update#
Update the alternatives table to include both Python 2.7.x and Python 3.5.x.First, we will list the available alternatives (most probably, you will get an empty list as seen in the screenshot below) We will use the update-alternatives command.
Note the versions available (first 2 digits only)

This guide is based and inspired from the following article by LinuxConfig: How to change from default to alternative Python version on Debian Linux. Until this changes, use the following recipe to get Python setup the way you want to. There are system dependencies which need Python 2 as well. You might be asking, whether it's maybe possible to have 1 version only? (and uninstall the previous version). This is annoying - this article tells you how to make Python 3 your default Python (so you can run: 'python mycode.py'). Now if you you want to develop in Python 3 (which we recommend), you need to specify the version of Python you are using (by running: 'python3 mycode.py'). The Pi (Raspbian) comes pre-installed with 2 versions of Python. If you see that your OS is using Python 2 by default, youll need to change it to use.
