python - Specific sequence stored in a list -

i looking way efficiently search lists have particular sequence of values. sequence important! example:

[x,y,z] , [x,z,y] contain same values sequence different

however:

• [x,y,z], [y,z,x] , [z,x,y] same me.
• [x,z,y], [z,y,x] , [x,z,y] same too.

i think bout running script parts of connections. example, if looking [x,y,z] look

mylist1 = ['a','b','c'] mylist2 = ['b','a','c'] def is_sequence_same(thelist,somelist):     if (thelist[0] == somelist[0] , thelist[1] == somelist[1]):        return true     if (thelist[1] == somelist[1] , thelist[2] == somelist[2]):         return true     if (thelist[0] == somelist[1] , thelist[1] == somelist[0]):         return false     if  (thelist[0] == somelist[2] , thelist[1] == somelist[2]):         return false     else:         return none is_sequence_same(mylist1,mylist2) 

function returns: true - if sequence same have asked, false - if sequence opposite

my current function incomplete. however, think there should more elegant ways of solving problem

use deque:

from collections import deque  def is_sequence_same(l1, l2):     if l1 == l2:         return true     if set(l1) != set(l2) or len(l1) != len(l2):         return false     d2 = deque(l2)     in range(len(l2)):         if l1 == list(d2):             return true         d2.rotate()     return false
