9 Best Practices for Python Enterprise Application Development

Learn best practices for Python enterprise application development, including managing dependencies, logging, unit testing, asynchronous programming, and deploying with Docker.

1. Managing Dependencies with Virtual Environments

In enterprise-level application development, projects often rely on multiple third-party libraries. To ensure the stability and portability of the project, using a virtual environment is the best option.

Steps:

1. Install `virtualenv`:

pip install virtualenv

2. Create a virtual environment:

virtualenv venv

3. Activate the virtual environment:
Windows:

venv\Scripts\activate

macOS/Linux:

source venv/bin/activate

Example:

# Install dependencies in the activated virtual environment
pip install requests

Explanation:
`virtualenv` is a tool for creating isolated Python environments.
After activating the virtual environment, all installed packages will be isolated within this environment, preventing any impact on the system’s global Python environment.
