: When combined with Pipfile.lock , you get "golden" environment definitions that ensure every developer on your team is using the exact same versions of every sub-dependency.

[[source]] url = "https://pypi.org" verify_ssl = true name = "pypi" [packages] requests = "*" flask = "==3.0.0" [dev-packages] pytest = "*" black = "^24.0" [requires] python_version = "3.11" Use code with caution. 1. [[source]]

Plus an autogenerated Pipfile.lock with full integrity hashes.

This blocks acts as your core application dependencies—packages strictly required for the production application to execute properly (e.g., requests or fastapi ). 3. [dev-packages] Pipfile

| Feature | requirements.txt | Pipfile | |---------|------------------|---------| | Environment separation | Manual naming (e.g., dev.txt ) | Built-in [dev-packages] section | | Version pinning | Manual == or loose >= | Semantic versioning ( ~= , * ) | | Hashing & security | ❌ No | ✅ SHA256 hashes via lock file | | CLI commands | pip install -r ... | pipenv install (automatic env management) | | Explicit source control | ❌ | ✅ Supports PyPI, private indexes, file paths |

When paired with Pipenv, the combination offers:

Run pipenv install . This creates a blank Pipfile. : When combined with Pipfile

. Introduced as a more robust replacement for the traditional requirements.txt , it allows developers to define direct dependencies

To start using Pipfile, you'll need to install Pipenv, which is the package manager that uses Pipfile. You can install Pipenv using pip:

: Lists dependencies only needed during development (e.g., pytest , black ). [[source]] Plus an autogenerated Pipfile

# Export production dependencies pipenv lock -r > requirements.txt
