If there is a lot of entries in the list, I would consider using an
indexed data structure such as dict.


ab=['a','b','c','d']
cd=['a','c']
common=[x.upper() for x in ab if x in cd]
ab_minus_cd=[x for x in ab if x not in cd]
cd_minus_ab=[x for x in ab if x not in cd]
requested_list = common+ab_minus_cd+cd_minus_ab- Hide quoted text -
