相同的散列键，不同的值:如何比较它们？

class HashTable:
    def __init__(self):
        self.size = 10
        self.table = [[] for _ in range(self.size)]

    def _hash(self, key):
        return hash(key) % self.size

    def insert(self, key, value):
        hash_key = self._hash(key)
        bucket = self.table[hash_key]
        for i, (k, v) in enumerate(bucket):
            if k == key:
                bucket[i] = (key, value)  # 更新现有键的值
                return
        bucket.append((key, value))  # 添加新键值对

    def get(self, key):
        hash_key = self._hash(key)
        bucket = self.table[hash_key]
        for k, v in bucket:
            if k == key:
                return v
        raise KeyError(key)

# 示例用法
hash_table = HashTable()
hash_table.insert("name", "Alice")
hash_table.insert("name", "Bob")  # 更新现有键的值

print(hash_table.get("name"))  # 输出: Bob
