The value between two list as shown below:

testlist = [1,3,5,7]
WinCombination = [ [7,5,3],[1,2,3],[3,5,7]]

I want to detect the value of [3,5,7] in WinCombination and it also exist in testArray = [1,3,5,7] with the same order. I cannot figure out the way to test between this list. I am beginner in Python. Thanks for helping

whatever i understood from your question that you want to find a combination from testList in wincombination with same order..may be below code can help you.

wincombination=[[1,2,3],[2,3,4],[6,5,4]]
testArray=[1,2,3,4]
flag=False
for i in wincombination:
    if i==testArray[1:]:
        print("present")
        flag=True
if flag==True:
    print("not present")

you should use itertools.combinations to get the combinations from the lenght, convert WinCombinations to a list of tuples and check every time if the combination is in the list.

in this case i used list comprehension in this case but you can also use the normal loop instead:

import itertools
testArray = [1,3,5,7]
WinCombination = [ [7,5,3],[1,2,3],[3,5,7]]
lentocheck=3

combined=[x for x in itertools.combinations(testArray,lentocheck) if x in list(map(tuple,WinCombination))]    
print(combined)

output:

[(3, 5, 7)]

i had to convert WinCombinations to a list of tuples because itertools.combinations returns a list of tuples, in this way i can do the comparison.

There is a simple way to get this done, it's just by comparing the str values of sequences.

str_test = str(testlist)[1:-1]
matches = [combination for combination in WinCombination
           if str(combination)[1:-1] in str_test]

this will match every sub-array from testlist that is present in WinCombination by verifying if the string of testlist is a superset of combination string, the slicing [1:-1] is just to keep out brackets from string.
