使用Python进行反向转换

import base64

encoded_str = 'SGVsbG8sIFdvcmxkIQ=='
decoded_bytes = base64.b64decode(encoded_str)
decoded_str = decoded_bytes.decode('utf-8')

print(decoded_str)  # 输出: Hello, World!

import json

json_str = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_str)

print(data)  # 输出: {'name': 'John', 'age': 30, 'city': 'New York'}

import pickle

# 假设我们有一个已序列化的pickle对象
serialized_data = pickle.dumps({'key': 'value', 'numbers': [1, 2, 3]})

# 反序列化
original_data = pickle.loads(serialized_data)

print(original_data)  # 输出: {'key': 'value', 'numbers': [1, 2, 3]}

import ast

list_str = "[1, 2, 3, 4]"
list_obj = ast.literal_eval(list_str)

print(list_obj)  # 输出: [1, 2, 3, 4]
