[Python-ideas] Objectively Quantifying Readability

[Tim Peters]

Objectively quantifying is easy.  For example,

def objective_readability_score(text):
    "Return the readability of `text`, a float in 0.0 .. 1.0"
    return 2.0 * text.count(":=") / len(text)

Then

>>> objective_readability_score("if value:")
0.0
>>> objective_readability_score("if value := f():")
0.125
>>> objective_readability_score(":=:=:=")
1.0

QED ;-)
