slytherin 2020.1.5

Python library of useful but lonely functions and classes

Slytherin

Slytherin is a collection of useful but lonely functions and classes that don't belong to other libraries.

Installation

pip install slytherin

Usage

get_size(obj)

The get_size() method calculates the memory footprint of a Python object recursively.

The exclude_objects argument is a list of objects and is optional with the default value of None. Any object in the exclude_objects list will be excluded from the recursive search. It can be used to avoid double counting the size when objects point to each other.

from slytherin import get_size
get_size(obj=[1,2,3], exclude_objects=None)

import pandas as pd
get_size(obj=pd.DataFrame({'id': range(1000), 'name':['Godric', 'Helga', 'Rowena', 'Salazar']*250}))

colour(text, text_colour, style, background_colour)

The colour() method can be used to add colour to printing text.

The colour are integers from 0 to 7:

• black: 0
• red: 1
• green: 2
• yellow: 3
• blue: 4
• purple: 5
• cyan: 6
• white: 7

The style argument is an integer between 0 and 5:

• normal: 0
• bold: 1
• underline: 2
• negative1: 3
• negative2: 5

from slytherin import colour
print(colour(text='Hello world!', text_colour=4))
