Advanced Python Scheduler (APScheduler) is a Python library that lets you schedule your Python code to be executed later, either just once or periodically.

You can add new jobs or remove old ones on the fly as you please. If you store your jobs in a database, they will also survive scheduler restarts and maintain their state. When the scheduler is restarted, it will then run all the jobs it should have run while it was offline.

Trend Micro Locality Sensitive Hash (TLSH) is a fuzzy matching library. Given a byte stream with a minimum length of 256 bytes, TLSH generates a hash value which can be used for similarity comparisons. Similar objects have similar hash values, which allows for the detection of similar objects by comparing their hash values. The byte stream should have a sufficient amount of complexity; for example, a byte stream of identical bytes will not generate a hash value.

Bleach is an easy whitelist-based HTML-sanitizing tool.

The functions and classes in humanfriendly can be used to make text interfaces more user-friendly. It includes tools to parse and format numbers, file sizes, and timespans, timers for long-running operations, menus to allow the user to choose from a list of options, and terminal interaction helpers.

Usage of Python's multiprocessing package in a gevent-powered application may raise problems. With gipc, process-based child processes can safely be created anywhere within a gevent-powered application.

This package provides a lightweight YAML Parser for Python. It supports only a chosen subset of the YAML format that is required to parse cookiecutter user configuration files. It does not have support for serializing into YAML and is not compatible with JSON.

The PyPNG module implements support for PNG images. It reads and writes PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 bits per pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, RGBA, LA (greyscale with alpha) with 8/16 bits per channel; colour mapped images (1/2/4/8 bit). Adam7 interlacing is supported for reading and writing. A number of optional chunks can be specified (when writing) and understood (when reading): tRNS, bKGD, gAMA.

PyPNG is not a high level toolkit for image processing (like PIL) and does not aim at being a replacement or competitor. Its strength lies in fine-grained extensive support of PNG features. It can also read and write Netpbm PAM files, with a focus on its use as an intermediate format for implementing custom PNG processing.

CustomTkinter provides fully customizable widgets, created and used like normal Tkinter widgets, which can also be used in combination with normal Tkinter elements.

Sorted Collections is a Python sorted collections library.

Confuse is a configuration library for Python that uses YAML. It takes care of defaults, overrides, type checking, command-line integration, human-readable errors, and standard OS-specific locations.

This Python tool figures out the differences between two similar XML files, in the same way the diff utility does it.

Cloup enriches Click with several features that make it more expressive and configurable such as option groups, constraints, subcommand aliases, subcommands sections and a themeable HelpFormatter.

Library for atomic file writes using platform dependent tools for atomic file system operations.

This package provides, in addition to the pyinotify Python library, a command line application exposing the same functionality.

python-flasgger allows extracting Swagger specs from your Flask project. It is a fork of Flask-Swagger.

Sphinx extension to support docstrings in Numpy format.

Fastprogress is a progress bar for Jupyter Notebook and console.

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

autoflake removes unused imports and unused variables from Python code as reported by pyflakes.

By default, it only removes unused imports for modules that are part of the standard library. Removal of unused variables is also disabled by default. It also removes useless pass statements.

This package provides a linter for the reStructuredText format.

This Python module provides a solver-agnostic abstraction for working with SMT formulas. For example, it allows manipulation and solving such formulas.

Inform is designed to display messages from programs that are typically run from a console. It provides a collection of ‘print’ functions that allow you to simply and cleanly print different types of messages.

The lazr.delegates package makes it easy to write objects that delegate behavior to another object. The new object adds some property or behavior on to the other object, while still providing the underlying interface, and delegating behavior.

Lmfit provides a high-level interface to non-linear optimization and curve fitting problems for Python. It builds on and extends many of the optimization methods of scipy.optimize. Initially inspired by (and named for) extending the Levenberg-Marquardt method from scipy.optimize.leastsq, lmfit now provides a number of useful enhancements to optimization and data fitting problems.
