我对python3.6中的内存错误有一些疑问

import itertools
input_list = ['a','b','c','d']
group_to_find = list(itertools.product(input_list,input_list))
a = []
for i in range(len(group_to_find)):
    if group_to_find[i] not in a:
       a.append(group_to_find[i])

    group_to_find = list(itertools.product(input_list,input_list))
MemoryError
