PyCharm Python Package Management: In-depth Understanding of Package Management Mechanisms to Enhance Development Efficiency

# 1. An Overview of Python Package Management

Python package management is a system for managing and distributing Python code and dependencies. It enables developers to easily install, uninstall, and update Python packages, thus simplifying the development process.

Python packages typically consist of multiple files, including Python modules, data files, and documentation. They are organized into a directory structure, where each directory represents a package. Packages can contain sub-packages, forming a hierarchical structure.

The Python package management system provides various functionalities, including:

- **Installing and uninstalling packages:** Allows developers to easily add packages to their projects or remove packages from them.
- **Managing dependencies:** Tracks dependencies between packages and automatically installs the required dependencies.
- **Updating and rolling back packages:** Enables developers to update packages to the latest version or roll back to previous versions.
