fake.py 0.1.2

Overview

fake.py is a standalone and portable library that allows you to generate various types of random data for testing and other purposes. The package provides a simplified, dependency-free alternative for generating random words, sentences, paragraphs, file names, URLs, person names, as well as bytes content for PDF-, DOCX- and various image files (such as PNG, SVG, BMP and GIF).

Requirements

• Python 3.8+

Differences with Faker

fake.py is modeled after the famous Faker package. Its’ API is highly compatible, although drastically reduced. It’s not multilingual and does not support postal codes or that many RAW file formats. However, you could easily include it in your production setup without worrying about yet another dependency.
