python : atexit and gnureadline not found by parser?

In kdevelop 5.4.5 of fedora 31, the kdevelop python parser gives me an 
module not found for atexit (python component) and also for gnureadline 
(which is installed). both can be imported and used ..
Does anyone encountered something like this? Is it something strange in 
my environment?

Thank you!
Adrian
