That mostly depend on what you have already installed previously. It took almost 3 hours because a lot of time is consumed in compiling the binaries and then installing python.įirst of all you need to get your dependencies right. The only issue while i faced during installation is the time taken for the whole process. $ python -VĪlso as time permits I suggest you to read the article. I have tried installing python 3.4 and 3.5 versions. The existing python distribution remains intact without issues. To get into the REPL of 3.5 type python3.5 on your terminal. In my case it was installed in the location /usr/local/bin/python3.5. Use which python3.5 command to get the binary location 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.I tried installing the python3.5.2 with the below steps and I was successful. One day, your Python version(s) will change. 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)

That means, if no manual alternative selection is made the alternative with the highest priority number will be set. 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.

#RASPEBERRY PI ZERO INSTALL PYTHON 3.6 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)

First of all, check which versions of Python your system has.

#RASPEBERRY PI ZERO INSTALL PYTHON 3.6 HOW TO#

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. Configure Default Python version on your Pi
