python3-stemmer-dbg 1.3.0+dfsg-2 (s390x binary) in ubuntu focal

 PyStemmer provides access to efficient algorithms for calculating a "stemmed"
 form of a word. This is a form with most of the common morphological endings
 removed; hopefully representing a common linguistic base form.
 .
 PyStemmer provides algorithms for several (mainly European) languages, by
 wrapping the libstemmer library from the Snowball project in a Python 3
 module.
 .
 This package contains the extensions built for the Python 3 debug interpreter.
