Jenkins Hash的Python实现？

def jenkins_hash(key):
    length = len(key)
    hash_value = 0
    for i in range(length):
        hash_value += ord(key[i])
        hash_value += (hash_value << 10)
        hash_value ^= (hash_value >> 6)
    hash_value += (hash_value << 3)
    hash_value ^= (hash_value >> 11)
    hash_value += (hash_value << 15)
    return hash_value

# 示例用法
key = "example_key"
hash_value = jenkins_hash(key)
print("Jenkins Hash值:", hash_value)
