Question

I have this python code which set A or B in a class. I want to print what this class receives:

if options.A:
   print "setting A"
   class TmpClass(A): pass
else:
   print "nothing set in the command line => setting to B"
   class TmpClass(B): pass

print "selected=",TmpClass

I want to see either A or B in the output but I see:

selected= TmpClass

Answer 1

What your code is doing, translated in English is:

if option.A has a value that evaluates to True:
    define an empty class called "TmpClass" that inherits from the object called "A"
otherwise:
    define an empty class called "TmpClass" that inherits from the object called "B"

Now, if what the code is actually doing is indeed what you intended, my guess is that what you wanted could be to know whether your class is A or B -based… If I am right, then the line you want to have at the end is:

print('TmpClass inherits from : %s' % TmpClass.__bases__)

HTH!
