Introduction to Pipfile

In the Python ecosystem, managing dependencies is crucial for ensuring that projects are reproducible and maintainable. Traditionally, requirements.txt files have been used to list project dependencies. However, with the introduction of Pipfile, a more robust and user-friendly approach to dependency management has emerged.

In this example, we've specified that our project requires Python 3.9 and has two dependencies: Flask and requests. We've also specified the versions of these dependencies using semantic versioning. Pipfile

pyproject.toml (PEP 621)

Version Specifiers You Can Use

package = "*"                 # Latest version
package = "==1.2.3"          # Exact version
package = ">=1.0,<2.0"       # Version range
package = "~=1.2.3"          # Compatible release (>=1.2.3, <1.3.0)
package = git = "https://github.com/user/repo.git"
package = editable = true, path = "./local-lib"

Improved dependency management: Pipfile allows you to declare dependencies with specific version requirements, making it easier to manage complex projects.
Support for multiple environments: Pipfile supports multiple environments, such as development and production, allowing you to specify different dependencies for each environment.
Hash checking: Pipfile supports hash checking, which helps ensure the integrity of your dependencies.
