python

The Python prompt should indicate “Anaconda, Inc.” in the version information, confirming you’re using the Anaconda Python distribution. Exit Python using quit() or Ctrl+D.

List installed packages to verify the Anaconda package collection:

conda list

This command shows all packages included in your base Anaconda environment, typically numbering in the hundreds.

Managing Anaconda Environments

Creating and Using Environments

Virtual environments prevent package conflicts and enable project-specific configurations. Create a new environment with a specific Python version:

conda create --name dataproject python=3.11

Activate your new environment to begin using it:

conda activate dataproject

Your command prompt will change to indicate the active environment name. This visual cue helps track which environment you’re currently using. Deactivate environments when switching between projects:

conda deactivate

List all available environments on your system:

conda env list

Environment management becomes crucial as you work on multiple projects with different requirements. Each environment maintains its own package versions and dependencies.

Package Management

Install packages using conda’s package manager, which handles dependencies automatically:

conda install numpy pandas matplotlib seaborn

For packages unavailable through conda, use pip within your conda environment:

pip install specific-package

Update all packages in your current environment:

conda update --all

Keep your base conda installation current with regular updates:

conda update conda

Export environment configurations for sharing or backup purposes:

conda env export > environment.yml

Recreate environments from exported files:

conda env create -f environment.yml
