如何消除python列表理解中的代码重复？

如何通过合并成一个列表来解决以下代码重复问题

 myList   =[ //someList      ]      
 thierList=[ //someOtherList ]      

 if name:
          [x for x in range(2,100) if x%2 and x in mylist and x not in theirList]

 else:
          [x for x in range(2,100) if x in mylist and x not in theirList] 

也可以使用集合

[x for x in range(2,100) if x in mylist and x not in theirList if not name or x%2 ]

set(myList + thierList)
