Okay so I've read that in python, the operators '++', '--' etc. are not implemented (like in c++). I also get the reason behind: they are not needed as often, thanks to iteration with range(8), and so on.
But then what exactly happens when someone does use them?
After testing:
c = 0
c = ++c # seemingly nothing changes
c = c++ # throws syntax error
you cannot use this operators, because they are not implemented
when you do c=++c, it is something like c= -c. The second changes the sign of the number. When you use + instead of -, it doesn't change the sign. ++c is the same operation applied twice, so c=++c is the same as c=c
