The Python FTP server library provides a high-level interface to write efficient, scalable and asynchronous FTP servers with Python. It is the most complete RFC-959 FTP server implementation available for Python, and has the following traits:

• It is lightweight, fast and scalable.

• It uses the sendfile(2) system call for uploads.

• It uses epoll, kqueue and select to handle concurrency asynchronously.

• It supports FTPS (RFC-4217), IPv6 (RFC-2428), Unicode file names (RFC-2640) and MLSD/MLST commands (RFC-3659).

• It has a flexible system of authorizers able to manage both virtual and real users.

Glances is a curses-based monitoring tool for a wide variety of platforms. Glances uses the PsUtil library to get information from your system. It monitors CPU, load, memory, network bandwidth, disk I/O, disk use, and more.

This module provides a nearly complete wrapping of the Oracle/Sleepycat C API for the Database Environment, Database, Cursor, Log Cursor, Sequence and Transaction objects, and each of these is exposed as a Python type in the bsddb3.db module. The database objects can use various access methods: btree, hash, recno, and queue. Complete support of Berkeley DB distributed transactions. Complete support for Berkeley DB Replication Manager. Complete support for Berkeley DB Base Replication. Support for RPC.

NumPy is the fundamental package for scientific computing with Python. It contains among other things: a powerful N-dimensional array object, sophisticated (broadcasting) functions, tools for integrating C/C++ and Fortran code, useful linear algebra, Fourier transform, and random number capabilities.

Boto3 is a Python library for writing programs that interact with AWS.

This package provides a library for parsing and validating OpenSSH public key files.

Autopage is a Python library to automatically display terminal output from a program in a pager such as less.

The extension-helpers package includes convenience helpers to assist with building Python packages with compiled C/Cython extensions. It is developed by the Astropy project but is intended to be general and usable by any Python package.

Mizani is a Python package for creating data visualizations. It provides functions and tools to help with the creation of visually appealing and informative visualizations, including scales, transformations and color palettes.

Requests-File is a transport adapter for use with the Requests Python library to allow local file system access via file:// URLs.

Blinker provides a fast dispatching system that allows any number of interested parties to subscribe to events, or "signals".

FontTools/TTX is a library to manipulate font files from Python. It supports reading and writing of TrueType/OpenType fonts, reading and writing of AFM files, reading (and partially writing) of PS Type 1 fonts. The package also contains a tool called “TTX” which converts TrueType/OpenType fonts to and from an XML-based format.

This package implements a functionality to print versions of imported Python packages.

pyaml is a PyYAML based python module to produce pretty and readable YAML-serialized data.

This package implements a functionality to convert between Python's datetime.timedelta and Golang's time.Duration formats.

python-beautifultable provides a class for easily printing tabular data in a visually appealing ASCII format to a terminal.

Features include, but are not limited to:

• Full customization of the look and feel of the table

• Row and column accessors.

• Full support for colors using ANSI sequences or any library.

• Plenty of predefined styles and option to create custom ones.

• Support for Unicode characters.

• Supports streaming table when data is slow to retrieve.

This package adds ANSI colors and decorations to your strings.

This package lets you read image and metadata from many bio-scientific formats such as plain TIFF, BigTIFF, OME-TIFF, STK, LSM, SGI,NIH, ImageJ, MicroManager, MD GEL, and FluoView files. It also lets you write numpy arrays to TIFF, BigTIFF, and ImageJ hyperstack compatible files.

This package provides a pure Python QR Code generator module. It uses the Python Imaging Library (PIL) to allow for the generation of QR Codes.

In addition this package provides a command line tool to generate QR codes and either write these QR codes to a file or do the output as ascii art at the console.

A library to identify devices (phones, tablets) and their capabilities by parsing (browser/HTTP) user agent strings.

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.

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.

This library implements algorithms and data structures for Lisp-style cons cells in Python.

A drop-in replacement for argparse that allows options to also be set via config files and/or environment variables.
