Create a new environment, installing named packages into it:

conda create {{[-n|--name]}} {{environment_name}} {{python=3.9 matplotlib}}

List all environments:

conda info {{[-e|--envs]}}

Activate an environment:

conda activate {{environment_name}}

Deactivate an environment:

conda deactivate

Delete an environment (remove all packages):

conda remove {{[-n|--name]}} {{environment_name}} --all

Install packages into the current environment:

conda install {{python=3.4 numpy}}

List currently installed packages in current environment:

conda list

Delete unused packages and caches:

conda clean {{[-a|--all]}}
