pip requirements.txt

pip requirements.txt is a text file used in Python projects to specify dependencies and their versions for installation via pip, the Python package installer. It lists packages with optional version constraints, enabling reproducible environments and dependency management. This file is commonly used with virtual environments to isolate project dependencies.

Also known as: requirements.txt, pip requirements file, Python dependencies file, pip install -r, requirements

Developers should use requirements.txt to ensure consistent dependency installation across different systems, such as in development, testing, and production environments. It is essential for Python projects to manage dependencies, facilitate collaboration, and automate deployments, particularly in web development, data science, and DevOps workflows.
