Remove duplicate sequence of integers from a list in Python

Question

I have a list of integers that I need to remove duplicate sequences, and logic makes my head.

I am trying to change this to what I need, however this only returns a single number related to the length of the repeating sequence, and it only counts with the starting integer.

This is how far I have come so far:

def findRep(rmRepList):
    #Array to hold [starting position, length] of repeating sequences
    repList = []
    #For each industry listed
    for industry in rmRepList:
        #Maximum starting position
        maxStartPos = len(industry)-2
        #For each possible starting point of repetition
        for start in range(1,maxStartPos):
            #Limit on how long the repetition can be
            maxLen = math.ceil((len(industry)-start)/2)

            #For each possible length (2 because already canceled out repeating resources in genAllLoop)
            for i in range(2,maxLen):
                #If the next 'i' integers repeat
                if industry[start:i+start] is industry[i+start:2*i+start]:
                    repList = [start,i]
                    industry = rmRep(repList, industry)

                #If reached end of list
                if 2*i+start+1 == len(industry):
                    #End loop
                    break

def rmRep(rmProp, loop):
    #Sequence of resources to drop
    rmSeq = [loop[rmProp[0]:rmProp[0]+rmProp[1]]]
    #Debugging statement
    print(rmSeq)
    loop.remove(rmSeq)
    return(loop)name = username_entry.get()

rmRepList is a list of lists containing each list that I need to parse.

So, for example, if a list is given

rmRepList = [[0,1,2,1,2,1,0],[0,1,2,1,2,1,2,3,4,5,3,4,5,6,0]]

I will need to return [[0,1,2,1,0], [0,1,2,3,4,5,6,0]]

listA = [0,1,2,1,2,1,2,3,4,5,3,4,5,6,0]
listB = [0,1,2,1,2,1,0]

def get_repeated_seq(seq, start, length):
    ref = seq[start:start+length]
    #print("Ref", ref)
    for pos in range(start+length, len(seq)-length):
        compare = seq[pos:pos+length]
        #print("Pos", pos, compare)
        if compare == ref:
            print("Found", ref, "at", pos)
            return pos
    return False

def get_repeated_seqs(seq):
    for size in reversed(range(2, len(seq)/2)):
        for pos in range(0, len(seq)-size):
            print("Check rep starting at pos %s for size %s" % (pos, size))
            get_repeated_seq(seq, pos, size)

print(get_repeated_seqs(listA))
