Python中TypeError:unhashable type:'dict'错误的解决办法

# 👇️ using dictionary as a key in a dictionary

# ⛔️ TypeError: unhashable type: 'dict'
my_dict = {'name': 'Jiyik', {'country': 'China'}: 'address'}

# 👇️ 使用字典作为集合中的元素

# ⛔️ TypeError: unhashable type: 'dict'
my_set = {{'name': 'Jiyik'}}

import json

# 👇️ 将字典转换为 JSON 字符串
my_json = json.dumps({'country': 'China'})

my_dict = {'name': 'Jiyik', my_json: 'address'}
print(my_dict)  # 👉️ {'name': 'Jiyik', '{"country": "China"}': 'address'}

# 👇️ 当你必须访问字典中的键时
print(my_dict[json.dumps({'country': 'Austria'})]) # 👉️ address

my_key = {'country': 'China'}
key = frozenset(my_key.items())
print(key)  # 👉️ frozenset({('country', 'China')})

my_dict = {'name': 'Jiyik', key: 'address'}


# 👇️ 当我们必须访问 key 时
print(my_dict[frozenset(my_key.items())])  # 👉️ 'address'

# 👇️ dict_items([('name', 'jiyik'), ('age', 30)])
print({'name': 'jiyik', 'age': 30}.items())

dict_key = {'id': 1, 'country': 'China'}

# ✅ 转换为元组
my_tuple = tuple(dict_key)
print(my_tuple)  # 👉️ ('id', 'country')

my_dict = {'name': 'Jiyik', my_tuple: 'address'}
print(my_dict)  # 👉️ {'name': 'Jiyik', ('id', 'country'): 'address'}

# 👇️ 当你必须访问字典中的键时
print(my_dict[my_tuple])  # 👉️ address

dict_value = {'id': 1, 'country': 'China'}

my_dict = {'name': 'Jiyik', 'data': dict_value}

# 👇️ {'name': 'Jiyik', 'data': {'id': 1, 'country': 'China'}}
print(my_dict)

print(my_dict['data'])  # 👉️ {'id': 1, 'country': 'China'}

another_dict = {'id': 1, 'country': 'China'}

my_dict = {'name': 'Jiyik'}

for key, value in another_dict.items():
    my_dict[key] = value

# 👇️ {'name': 'Jiyik', 'id': 1, 'country': 'China'}
print(my_dict)

my_dict = {'id': 1,  'name': 'Jiyik'}

# 👇️ dict_items([('id', 1), ('name', 'Jiyik')])
print(my_dict.items())

print(hash('jiyik.com'))  # 👉️ 4905958875846995527

# ⛔️ TypeError: unhashable type: 'dict'
print(hash({'name': 'Jiyik'}))

my_dict = {'name': 'Fql'}

my_dict['name'] = 'Jiyik'

print(my_dict) # 👉️ {'name': 'Jiyik'}

my_dict = {'name': 'Jiyik'}

print(type(my_dict))  # 👉️ <class 'dict'>
print(isinstance(my_dict, dict))  # 👉️ True

my_str = 'jiyik.com'

print(type(my_str))  # 👉️ <class 'str'>
print(isinstance(my_str, str))  # 👉️ True
