Pylexique is a Python wrapper around Lexique383.
It allows the extraction of lexical information from more than 140 000 French words in an Object Oriented way.

Pylexique est une librairie Python encapsulant Lexique383.
Cette librairie permet d’extraire l’information lexicale de plus de 140 000 mots Français de manière Orientée Objet.
Each lexical item is represented as a LexItem having the following LexEntryType:

Chaque entrée lexicale est représentée par un LexItem de type LexEntryType:
