哈希表是一种数据结构,用于存储键值对。以下是一个使用 Python 实现的简单哈希表:

```python

class HashTable:

def __init__(self):

= 10

= []

= []

def hash_function(self, key):

sum = 0

for i in range(len(key)):

sum += ord(key[i])

return sum %

def rehash(self, old_hash):

return (old_hash + 1) %

def put(self, key, data):

hash_value = _function(key)

if [hash_value] is None:

[hash_value] = key

[hash_value] = data

else:

[hash_value] = data

(hash_value)

def get(self, key):

hash_value = _function(key)

if [hash_value] == key:

return [hash_value]

else:

(hash_value)

return None

def delete(self, key):

hash_value = _function(key)

if [hash_value] == key:

[hash_value] = None

[hash_value] = None

else:

(hash_value)

def display(self):

for i in range():

if [i] is not None:

print(f"{[i]} : {[i]}")

# 示例

hash_table = HashTable()

hash_("apple", "fruit")

hash_("ball", " toy")

hash_("cat", "animal")

hash_y()

print(hash_("apple")) # 输出:fruit

print(hash_("ball")) # 输出:toy

print(hash_("cat")) # 输出:animal

hash_("ball")

hash_y()

```
