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.

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

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

>>> from mpu.datastructures import EList

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

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

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

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))

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

net_income = gross_income * Fraction("0.80")

print(savings)

prints 1375.31 Euro
