C3 Linearization in Method Resolution Order (MRO)

In this tutorial, we'll learn C3 Linearization algorithm used in Method Resolution Order.
We'll manually calculate the the MRO for a class and compare with the one generated python interpreter.

The code used in this tutorial is available here-

Thank you so much. My search for how MRO works, ends here! +1. BTW, it's worth mentioning that when we can't merge further, Python will raise an exception. For example, if we encounter this merge somewhere in the process: merge(XYO, YXO), it'll raise an exception. Because X is in tail of YXO and Y is in the tail of XYO. So nothing can be done further.

very one question in merge(DFO, CDEO, C) you are not choosind D because D is first in first list but 2nd in second list so not a good head but why are you chooing C because in second list it's first that's ok but in third list it both first and last so that's the part confusing me in case of single element in the list like only C ? can you clarify please?
