mpu

Martins Python Utilities (mpu) is a collection of utility functions and classes with no other dependencies.

The total size of the package will never be bigger than 10 MB and currently it is 120 kB in zipped form. This makes it a candidate to include into AWS Lambda projects.

Installation

$ pip install git+https://github.com/MartinThoma/mpu.git

It can, of course, also be installed via PyPI.

Usage

Datastructures

>>> from mpu.datastructures import EList

>>> l = EList([2, 1, 0])
>>> l[2]
0

>>> l[[2, 0]]
[0, 2]

>>> l[l]
[0, 1, 2]

Shell

To enhance your terminals output, you might want to do something like:

from mpu.shell import Codes

print("{c.GREEN}{c.UNDERLINED}Works{c.RESET_ALL}".format(c=Codes))

Quick Examples

Creating small example datastructures is a task I encounter once in a while for StackExchange answers.

from mpu.pd import example_df

df = example_df()
print(df)

gives

     country   population population_time    EUR
0    Germany   82521653.0      2016-12-01   True
1     France   66991000.0      2017-01-01   True
2  Indonesia  255461700.0      2017-01-01  False
3    Ireland    4761865.0             NaT   True
4      Spain   46549045.0      2017-06-01   True
5    Vatican          NaN             NaT   True

Money

import mpu
from fractions import Fraction

gross_income = mpu.units.Money("2345.10", "EUR")
net_income = gross_income * Fraction("0.80")
apartment = mpu.units.Money("501.23", "EUR")
savings = net_income - apartment
print(savings)

prints 1375.31 Euro
