how to solve memory

[meInvent bbird]

it is quite ridiculous, 
this time i am sure that i put correct indentation
and add a else statement to make sure recursive call inside the 
if statement , it still memory error, 

where is the memory error?

is itertools.combinations so big for the list?


  if deep == maxx:
   if deep > 0:
    b = []
    for aaa,bbb in itertools.combinations(initlist, 2):     
     b.append([str(i)+str(j) for i,j in zip(aaa, bbb)])
    print("deep=")
    print(deep)
    path2 = DFS(b, deep-1, maxx, sourceoperators, path)
    path.append(path2)
   else:
    print ""
  else:
   if deep > 0:
    for aaa,bbb in itertools.combinations(initlist, 2):
     b.append([str(i)+str(j) for i,j in zip(aaa, bbb)])
    print("deep=")
    print(deep)
    path2 = DFS(b, deep-1, maxx, sourceoperators, path)
    path.append(path2)
   else:
    print ""
 return path
