## Add a Python 2.x environment
## Add a custom conda environment and Jupyter kernel
Python 2.x was removed from all images on August 10th, 2017, starting in tag `cc9feab481f7`.
You can add a Python 2.x environment by defining your Dockerfile inheriting from one of the images like so:
```dockerfile
# Choose your desired base image
FROM jupyter/scipy-notebook:latest
# Create a Python 2.x environment using conda, including the ipython kernel
# and the kernda utility. Add any additional packages you want available for use
# in a Python 2 notebook to the first line here (e.g., pandas, matplotlib, etc.)
RUN mamba create --quiet --yes -p "${CONDA_DIR}/envs/python2" python=2.7 ipython ipykernel kernda && \
mamba clean --all -f -y
USER root
# Create a global kernelspec in the image and modify it so that it properly activates
# the python2 conda environment.
RUN "${CONDA_DIR}/envs/python2/bin/python" -m ipykernel install && \
"${CONDA_DIR}/envs/python2/bin/kernda" -o -y /usr/local/share/jupyter/kernels/python2/kernel.json
USER ${NB_UID}
```

## Add a Python 3.x environment
The default version of Python that ships with conda/ubuntu may not be the version you want.
The instructions to add a conda environment with a different version and make it accessible to Jupyter are very similar to Python 2.x. Still, they are slightly simpler (no need to switch to `root`):
The default version of Python that ships with the image may not be the version you want.
The instructions below permit to add a conda environment with a different Python version and make it accessible to Jupyter.
```dockerfile
# Choose your desired base image
FROM jupyter/minimal-notebook:latest
# name your environment and choose python 3.x version
# name your environment and choose the python version
ARG conda_env=python37
ARG py_ver=3.7
