To install dparse, run:

$ pip install dparse

If you want to update Pipfiles, install the pipenv extra:

$ pip install dparse[pipenv]


To use dparse in a Python project:

from dparse import parse, filetypes

content = """
South==1.0.1 --hash=sha256:abcdefghijklmno

df = parse(content, file_type=filetypes.requirements_txt)


  "file_type": "requirements.txt",
  "content": "\nSouth==1.0.1 --hash=sha256:abcdefghijklmno\npycrypto>=2.6\n",
  "path": null,
  "sha": null,
  "dependencies": [
      "name": "South",
      "specs": [
      "line": "South==1.0.1 --hash=sha256:abcdefghijklmno",
      "source": "pypi",
      "meta": {},
      "line_numbers": null,
      "index_server": null,
      "hashes": [
      "dependency_type": "requirements.txt",
      "extras": []
      "name": "pycrypto",
      "specs": [
      "line": "pycrypto>=2.6",
      "source": "pypi",
      "meta": {},
      "line_numbers": null,
      "index_server": null,
      "hashes": [],
      "dependency_type": "requirements.txt",
      "extras": []

Python 2.7

This tool requires latest Python patch versions starting with version 3.5. We did support Python 2.7 in the past but, as for other Python 3.x minor versions, it reached its End-Of-Life and as such we are not able to support it anymore.

We understand you might still have Python 2.7 projects running. At the same time, Safety itself has a commitment to encourage developers to keep their software up-to-date, and it would not make sense for us to work with officially unsupported Python versions, or even those that reached their end of life.

If you still need to use Safety with Python 2.7, please use version 0.4.1 of Dparse available at PyPi. Alternatively, you can run Safety from a Python 3 environment to check the requirements file for your Python 2.7 project.


0.5.1 (2020-04-26)

  • Fixed package metadata removing 2.7 support
  • Install pipenv only when asked for with extras

0.5.0 (2020-03-14)

A bug with this package allows it to be installed on Python 2.7 environments, even though it should not work on such version. You should stick with version 0.4.1 version instead for Python 2.7 support.

  • Dropped Python 2.7, 3.3, 3.4 support
  • Removed six package
  • Removed pinned dependencies of tests
  • Dropped tests support in favor of tox

0.4.1 (2018-04-06)

  • Fixed a packaging error.

0.4.0 (2018-04-06)

  • pipenv is now an optional dependency that’s only used when updating a Pipfile. Install it with dparse[pipenv]
  • Added support for invalid toml Pipfiles (thanks @pombredanne)

0.3.0 (2018-03-01)

  • Added support for setup.cfg files (thanks @kexepal)
  • Dependencies from Pipfiles now include the section (thanks @paulortman)
  • Multiline requirements are now ignored if they are marked
  • Added experimental support for Pipfiles

0.2.1 (2017-07-19)
