python-simplejson-dbg 3.13.2-1 (amd64 binary) in ubuntu bionic

 simplejson is a simple, fast, complete, correct and extensible JSON
 <http://json.org> encoder and decoder.
 .
 The encoder may be subclassed to provide serialization in any kind of
 situation, without any special support by the objects to be serialized
 (somewhat like pickle).
 .
 The decoder can handle incoming JSON strings of any specified encoding
 (UTF-8 by default).
 .
 simplejson is the externally maintained development version of the json
 library included with Python 2.6 and Python 3.0, but maintains backwards
 compatibility with Python 2.5.
 .
 This package contains the extension built for the Python 2 debug interpreter.
