destruction

Destroy Python programs with just a single import statement! Sounds fun, doesn't it?

destruction is a simple module that will silently destroy a lot of Python programs by manipulating values over time. For example, if you define a float variable and then do some operations over time, you'll be in for a surprise.

>>> import destruction
>>> n1 = float(0.5)
>>> n2 = float(0.5)
>>> n1 + n2
0.9948744748218606
>>> n1 + n2
1.0009324588178117
>>> n1 + n2
0.9956876734263913
>>> n1 + n2
1.009620798598302

What kind of sorcery is this?

Python has a module called __builtin__ (it's called builtins in Python 3) which contains all kinds of basic things. For example, the float class resides in there.

destruction switches these classes for custom ones that do weird stuff to break your program. For example, the __add__ member function is overridden with a custom one that adds a tiny, but non-zero number to the result. So it's always wrong!

Installation

$ pip install destruction

Usage

To make the lives of your arch enemies miserable, sneak in the following line anywhere in their Python code:

import destruction

Examples

Varying π and e

You saw the float example. Let's do something weirder:

>>> import destruction
>>> import math
>>> math.pi
3.1349545779223096
>>> math.pi
3.1332825202115226
>>> math.pi
3.1332205700116864
>>> math.pi
3.1346367856853625
>>> math.pi
3.130824304762861

pi that slightly changes everytime you access it. Evil, I know. Same with e:

>>> math.e
2.718878169620603
>>> math.e
2.723038508262948
>>> math.e
2.7308532846593865

The only caveat is that you must import math after you import destruction. Slightly inconvinient, I admit.
