python split list to elem

# initializing list 
test_list = [1, 4, 5, 6, 4, 5, 6, 5, 4] 
  
# printing original list 
print("The original list : " + str(test_list)) 
  
# using list comprehension + zip() + slicing + enumerate() 
# Split list into lists by particular value 
size = len(test_list) 
idx_list = [idx + 1 for idx, val in
            enumerate(test_list) if val == 5] 
  
  
res = [test_list[i: j] for i, j in
        zip([0] + idx_list, idx_list + 
        ([size] if idx_list[-1] != size else []))] 
  
# print result 
print("The list after splitting by a value : " + str(res)) 
Output :

The original list : [1, 4, 5, 6, 4, 5, 6, 5, 4]
The list after splitting by a value : [[1, 4, 5], [6, 4, 5], [6, 5], [4]]
