new-dale-chall-readability 1.0.9

An implementation of the New Dale-Chall readability formula which closely follows the specification.

The new Dale-Chall readability formula

In a nutshell:

pip install new-dale-chall-readability

In [1]: from new_dale_chall_readability import cloze_score, reading_level

In [2]: text = (
   ...:     'Latin for "friend of the court." It is advice formally offered '
   ...:     'to the court in a brief filed by an entity interested in, but not '
   ...:     'a party to, the case.'
   ...:     )

In [3]: cloze_score(text)
Out[3]: 42.46652

In [4]: reading_level(text)
Out[4]: '5-6'

This implementation closely follows the specification, directly from the book's text (Chall & Dale, 1995). The test cases are also directly from the book.
