pocketwelt

Python powertool in your pocket 🔨

Introduction

pocketwelt purpose is to provide basic tools for Python projects.

Idea for this package came from my personal experience of repeating certain methods over and over again - quite simple, but yet too complex to keep them in my memory at all times.

Hopefully pocketwelt will help you as it helps me - as a pocekt tool that comes in handy when I want to kickstart development as fast as possible or simply forgot about simple base64 encoding ;)

Worth noting - package uses only built-in Python libraries. My purpose is to keep this as vanilla as possible, so it does not collide with other dependencies you might have in your project.

Installation

pocketwelt is available on PyPi and you can install it via pip:

pip install pocketwelt

You can also install it straight from git:

pip install git+https://github.com/neurowelt/pocketwelt.git

Usage

Since this package is built using only vanilla Python libraries you can start using it right away after installing! Check out a few examples to get you going:

• Custom colored logger
• Pickle your custom class
• Decode base64 images

Custom colored logger

pocketwelt comes with a neat CustomLogger class that provides colored logs and simple file based logging. You can create as many loggers as you want by simply calling the following method:

from pocketwelt import getCustomLogger

error_logger = getCustomLogger("Error Logger", "ERROR")
info_logger = getCustomLogger("Info Logger", "INFO")

# Use as usual
error_logger.error("Error")
error_logger.info("Info that won't log")
info_logger.info("Info")

Pickle your custom class

Often times when working with large dictionaries that contain more complex types you may want to save your current class for later to quickly reload it. You can more than easily use the following methods to do this:

from pocketwelt import save_pickle, load_pickle
from your_script.complex_class import CustomClass

# Perform some operations with your class
llm = CustomClass()
llm.func()
llm.calc()

# Save object for later
save_pickle(llm, "llm.pkl")

# Reload it back
llm = load_pickle("llm.pkl")

Decode base64 images

You never know when you're going have to decode some base64 objects - that's where the encodings module comes in! For example, decoding base64 image to PIL.Image never have been easier:

from pocketwelt import b64_decode
from PIL import Image

decoded_obj = b64_decode(b64_image)
image = Image.open(decoded_obj)

Tip

Check out the official documentation to read in detail about every single method and their limitations!

Notes

When going through the tests directory you will find a painting of Gandalf (see original) that I use for testing. It was created by Jef Murray, a reknown fantasy illustrator. I recommend visiting his site to see more of his work.
