conda update anaconda

🏝Managing Environments

Get a list of all my environments, Active environment shown with *

conda info --envs

conda info -e

Create an environment and install program(s)

conda create --name snowflakes biopython

conda create -n snowflakes biopython

Activate the new environment to use it

conda activate snowflakes

Deactivate the environment

conda deactivate

Create a new environment, specify Python version

conda create -n bunnies python=3.4 astroid

Make exact copy of an environment

conda create -n flowers --clone snowflakes

Delete an environment

conda remove -n flowers --all

Save current environment to a file

conda env export > puppies.yml

Load environment from a file

conda env create -f puppies.yml

⚙Managing Python

Check versions of Python available to install

conda search --full-name python

conda search -f python

Install different version of Python in new environment

conda create -n snakes python=3.4

📝Managing .condarc Configuration

Get all keys and values from my .condarc file
