Library to calculate Python functions cognitive complexity via code.


pip install cognitive_complexity

Tested on python 3.7 and 3.6.


>>> import ast

>>> funcdef = ast.parse("""
... def f(a):
...     return a * f(a - 1)  # +1 for recursion
... """).body[0]

>>> from cognitive_complexity.api import get_cognitive_complexity
>>> get_cognitive_complexity(funcdef)

What is cognitive complexity

Here are some readings about cognitive complexity:

Realization details

This is not precise realization of original algorithm proposed by G. Ann Campbell, but it gives rather similar results. The algorithm gives complexity points for breaking control flow, nesting, recursion, stacks logic operation etc.
