python string转dict

str_dict = '{"name": "Alice", "age": 30, "city": "Beijing"}'

# 使用eval函数将字符串转换为字典
dict_data = eval(str_dict)

print(dict_data)

{'name': 'Alice', 'age': 30, 'city': 'Beijing'}

import json

str_json = '{"name": "Bob", "age": 25, "city": "Shanghai"}'

# 使用json模块将字符串转换为字典
dict_data = json.loads(str_json)

print(dict_data)

{'name': 'Bob', 'age': 25, 'city': 'Shanghai'}

str_dict = '{"name": "Charlie", "age": 35, "city": "Guangzhou"}'

# 使用字典推导式将字符串转换为字典
dict_data = {k: v for k, v in (item.split(': ') for item in str_dict[1:-1].split(', ')}}

print(dict_data)

{'name': 'Charlie', 'age': 35, 'city': 'Guangzhou'}
