Project description


Flesch Kincaid readability score for text

A Python module implementation of the Flesch Kincaid readability score algorithm.

The source code is released under the MIT License.


pip3 install fkscore


For text in python represented as a string.

Takes text as string datatype. Words can be on same or different lines. Current version is English language only. Email for support.

import fkscore
text = '...blah blah blah...'
f = fkscore.fkscore(text)


from fkscore import fkscore
text = '...blah blah blah...'
f = fkscore(text)


Output includes 2 dictionaries of information as follows:

  • stats:
    • stats['num_words']
    • stats['num_syllables']
    • stats['num_sentences']
  • score:
    • score['readability'] # Calculated F-K Readability Score
    • score['grade'] # Permuted F-K Grade Reading Level


Releases and additions will push to PyPi periodically, but if there is a feature in master not built/pushed and you want it to be, just ping me.


This is a maintained as an implementation of the Flesch-Kincaid readability algorithm which was initially developed in 1948 by Rudolph Flesch and later revised by the U.S. Navy in 1975. This module is pure python and works with 3.5+.


Feel free to ping for questions, comments, concerns or interact directly via the GitHub repository.
