How to install python with conda?

I'm trying to install python 3.9 in a conda enviroment. I tried creating a new conda env using the following command,

conda create --name myenv python=3.9

But I got an error saying package not found because python 3.9 is not yet released

So, I manually created a folder in envs folder and tried to list all envs. But I couldn't get the manually created new environment.

So, how do I install python 3.9 in a conda env with all functionalities like pip working?

To create python 3.10 conda environment use the following command

conda create -n py310 python=3.10

py310 - environment name

Update 2

You can now directly create python 3.9 environment using the following command

conda create -n py39 python=3.9

py39 - environment name

Update 1

Python 3.9 is now available in conda-forge.

To download the tar file - https://anaconda.org/conda-forge/python/3.9.0/download/linux-64/python-3.9.0-h852b56e_0_cpython.tar.bz2

Anaconda Page - https://anaconda.org/conda-forge/python

As pointed out in the comments, python 3.9 is not yet there on any channels. So, it cannot be install yet via conda.

Instead, you can download the python 3.9 executable and install it.

Once the installation is done, a new executable will be created for python 3.9 and pip 3.9 will be created.

Python:

python3.7
python3.7-config
python3.7m
python3.7m-config
python3.9
python3.9-config

pip

pip
pip3
pip3.7
pip3.8
pip3.9
pipreqs

In order to install ipython for python 3.9,

pip3.9 install ipython

On 6-Oct-2020, Python 3.9 was made available on conda-forge: https://anaconda.org/conda-forge/python. However, most of the other packages (including some of the essentials to create a basic environment) didn't explicitly support Python 3.9 yet.

However (as of 15-Oct-2020), the basic dependencies appear to have been fixed and the following command now works:

conda create -c conda-forge python=3.9 -n py39-demo

You can now simply just run

conda create --name myenv python=3.9

And it will create your python 3.9 virtual environment simply.
