Managing Python
===============
Conda treats Python the same as any other package, so it is easy
to manage and update multiple installations.
Conda supports Python 3.10, 3.11, 3.12, and 3.13.
Viewing a list of available Python versions
===========================================
To list the versions of Python that are available to install,
in your terminal window, run::
conda search python
This lists all packages whose names contain the text ``python``.
To list only the packages whose full name is exactly ``python``,
add the ``--full-name`` option. In your terminal window, run::
conda search --full-name python
Installing a different version of Python
=========================================
To install a different version of Python without overwriting the
current version, create a new environment and install the second
Python version into it:
#. Create the new environment:
* To create the new environment for Python 3.9, in your terminal
window run:
.. code-block:: bash
conda create -n py39 python=3.9
.. note::
Replace ``py39`` with the name of the environment you
want to create. ``python=3.9`` is the package and version you
want to install in this new environment. This could be any
package, such as ``numpy=1.19``, or :ref:`multiple packages
<installing multiple packages>`.
#. :ref:`Activate the new environment <activate-env>`.
#. Verify that the new environment is your :ref:`current
environment <determine-current-env>`.
#. To verify that the current environment uses the new Python
version, in your terminal window, run:
.. code::
python --version
Installing PyPy
===============
To use the PyPy builds you can do the following::
conda config --add channels conda-forge
conda config --set channel_priority strict
conda create -n pypy pypy
conda activate pypy
Using a different version of Python
====================================
To switch to an environment that has different version of Python,
:ref:`activate the environment <activate-env>`.
Updating Python
===============
To update Python to the latest version in your environment, run::
conda update python
This command will update you to the latest major release (e.g. from ``python=3.10`` to ``python=3.12``).
If you would like to remain on a minor release, use the ``conda install`` command instead::
conda install python=3.10
