def solution(want, number, discount):
    answer = 0
    # want = ["banana", "apple", "rice", "pork", "pot"]
    # number = [3, 2, 2, 2, 1] ==> 개수
    # discount = ["chicken", "apple", "apple", "banana", "rice", "apple", "pork", "banana", "pork", "rice", "pot", "banana", "apple", "banana"]
    
    hash_table = {}
    for key, value in zip(want, number):
        hash_table[key] = value
    # print(hash_table)
    
    k=0
    while True:
        if k > len(discount)-10:
            break
        idx_discount = discount[k:k+10]
        idx = Counter(idx_discount)
        # print(idx)
        if idx == hash_table:
            answer+=1
            k+=1
        else:
            k+=1
    
    return answer

==> 문자열 슬라이싱 idx_discount 생성이후 Counter() 통한 해쉬 생성
