This library allows standard Python logging to output log data as JSON objects. With JSON we can make our logs more readable by machines and we can stop writing custom parsers for syslog-type records.

This package provides a streaming multipart parser for Python.

This package is a recursive descent parsing library for Python based on functional combinators. Parser combinators are just higher-order functions that take parsers as their arguments and return them as result values.

This package provides a YAML template engine with Python expressions.

TatSu (竜) takes a grammar in a variation of Extended Backus-Naur Form (EBNF) as input, and outputs a memoizing Parsing Expression Grammar (PEG) or Packrat parser in Python.

Click is a package for creating powerful and beautiful command line interfaces (CLI) in Python, but it has no the functionality for creating option groups. The aim of this package is to provide group options with extensible functionality using canonical and clean API (Click-like API as far as possible).

This package provides a Python module for parsing and splitting PEM files.

This package provides Python bindings and utilities for GeoJSON, a format for encoding geographic data structures.

When using matplotlib and plotting more than one line, it is common to want to be able to want to be able to cycle over one or more artist styles; but the plotting logic can quickly become involved. To address this and enable easy cycling over arbitrary kwargs, the Cycler class was developed.

Pykka implements the actor model in Python, which introduces some simple rules to control the sharing of state and cooperation between execution units, and makes it easier to build concurrent applications.

Exrex is a command line tool and Python module that generates all, or random, matching strings to a given regular expression.

This package provides support for the APA style within pybtex.

psutil (Python system and process utilities) is a library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap.

This package provides a scalable Bloom filter implemented in Python.

Simple decorator to set attributes of target function or class in a DRY way.

Python-Titlecase is a Python port of John Gruber's titlecase.pl. It capitalizes (predominantly English) strings in a way that is similar to book titles, using the New York Times Manual of Style to leave certain words lowercase.

The aim of the wrapt module is to provide a transparent object proxy for Python, which can be used as the basis for the construction of function wrappers and decorator functions.

This package provides a decorator which makes caching time-or-computationally-expensive properties quick and easy and works in Python 2 or 3.

This package provides a utility to find Python versions on the current system.

JUBE helps perform and analyze benchmarks in a systematic way. For each benchmarked application, benchmark data is stored in a format that allows JUBE to deduct the desired information. This data can be parsed by automatic pre- and post-processing scripts that draw information and store it more densely for manual interpretation.

python-json2html is a python module to convert JSON into a human readable HTML table representation.

This package implements a functionality to cache on disk the result of expensive calculations. It was started as part of Pint, the Python units package.

The semantic_version class is a small library for handling semantic versioning (SemVer) in Python.

It can compare versions, generate a new version that represents a bump in one of the version levels, and check whether any given string is a proper semantic version identifier.
