Python environments with Anaconda

Conda allows you to create separate environments, each containing their own files, packages, and package dependencies. The contents of each environment do not interact with each other.

The most basic way to create a new environment is with the following command:

conda create --name <env-name>

To add packages while creating an environment, specify them after the environment name:

conda create --name <env_name> python numpy pandas
conda create --name <env_name> python==3.11 pandas==2.2.2 seaborn==0.13.2 matplotlib==3.8.4
conda activate <env_name>

conda create --name envpython311 python==3.11 pandas==2.2.2 seaborn==0.13.2 matplotlib==3.8.4
conda activate envpython311

For more information on working with environments, see Managing environments.
