The flufl.lock package provides NFS-safe file locking with timeouts for POSIX systems. It is similar to the O_EXCL option of the open system call but uses a lockfile. Lock objects support lock-breaking and have a maximum lifetime built-in.

This package contains typing stubs for TOML, a very small subset the Python stubs contained in the complete typeshed collection.

This package provides a Stream and Optional class.

This package lets you parse Python docstrings in reST, Google and Numpydoc format.

This package contains a library for ordered multivalue dictionaries. A multivalue dictionary is a dictionary that can store multiple values for the same key. An ordered multivalue dictionary is a multivalue dictionary that retains the order of insertions and deletions.

Cheetah is a text-based template engine and Python code generator.

Cheetah can be used as a standalone templating utility or referenced as a library from other Python applications. It has many potential uses, but web developers looking for a viable alternative to ASP, JSP, PHP and PSP are expected to be its principle user group.

Features:

1. Generates HTML, SGML, XML, SQL, Postscript, form email, LaTeX, or any other text-based format.

2. Cleanly separates content, graphic design, and program code.

3. Blends the power and flexibility of Python with a simple template language that non-programmers can understand.

4. Gives template writers full access to any Python data structure, module, function, object, or method in their templates.

5. Makes code reuse easy by providing an object-orientated interface to templates that is accessible from Python code or other Cheetah templates. One template can subclass another and selectively reimplement sections of it.

6. Provides a simple, yet powerful, caching mechanism that can dramatically improve the performance of a dynamic website.

7. Compiles templates into optimized, yet readable, Python code.

Redo provides various means to add seamless ability to retry to any Python callable.

Shellingham detects what shell the current Python executable is running in.

Docspec is a JSON object specification for representing API documentation of programming languages.

The pip-run command provides on-demand temporary package installation for a single interpreter run. It replaces this series of commands:

$ virtualenv --python pythonX.X --system-site-packages /tmp/env
$ /tmp/env/bin/pip install pkg1 pkg2 -r reqs.txt
$ /tmp/env/bin/python ...
$ rm -rf /tmp/env

This package is a wrapper around argparse, allowing you to write complete CLI applications in seconds while maintaining all the flexibility.

This package contains a small collection of test tool plugins for nose2 and flake8.

heapdict implements the MutableMapping ABC, meaning it works pretty much like a regular Python dict. It’s designed to be used as a priority queue.

JSON5 extends the JSON data interchange format to make it slightly more usable as a configuration language. This Python package implements parsing and dumping of JSON5 data structures.

The Scooby package reports the following information about the currently running system:

• operating system name;

• hardware information including machine type (e.g., i386, x86_64, etc.), CPU count and total RAM;

• Python environment (e.g., Python, IPython, etc.);

• file system name;

• Python version;

• versions of specified Python packages.

It can generate reports as HTML tables or plain text lists.

Scooby has no required dependencies, and only few optional dependencies.

smmap is a pure Python implementation of a sliding window memory map manager.

Mimeparse provides basic functions for parsing MIME type names and matching them against a list of media-ranges.

Library to make reading, writing and modifying both binary and ascii STL files, file format native to the stereolithography CAD software created by 3D Systems, easy.

This package provides provides drop-in replacements for the Python built-in int and float that are on par or faster with the Python equivalents.

Google Text-to-Speech (gTTS) is a Python library and CLI tool to interface with the Google Translate text-to-speech API. It lets you write spoken MP3 data to a file, a file-like object (bytestring) for further audio manipulation, or stdout.

This package provides a spec-compliant gitignore parser for Python.

The executor package is a simple wrapper for Python’s subprocess module that makes it very easy to handle subprocesses on UNIX systems with proper escaping of arguments and error checking currently doing, particularly the AST node being executed.

validate_email can be used to verify if an email address is valid and really exists.
