The best way to search for the simple plugins and to see how they work and and try to imitate them and a lot you will by googling
to start with you have to learn basic python and if know other program language will be very helpful
and next how to create enigma screens.
many plugins contain python part enigma part and good routine to separate pure python code in separate files from enigma files and enigma importing statement,may difficult to understand this part now but to know you can debug python files in windows python and then move to the box
no simple way to debug codes other than box,for me because i hate to set with laptop in front of tv i use frequently pc open webif(and is fantastic for this job) to navigate by webif remote to menu,plugin and take action then with aid of pc ftp program you can edit the box code(i like WinSCP) which open the plugin py files in windows python idle
this my way learned myself after few years for working with plugins
some links windows python https://www.python.o...se/python-2713/ better this version because version 3.xxx not used enigma2 boxes
