Global Access

In Python, mutable data types like lists and dictionaries are passed by reference. When you pass a list or dictionary to a function, what you are actually passing is a reference to the original data. Therefore, when you modify the data inside the function, it affects the same piece of data, resulting in changes to the data outside the function as well.

def modify_data(my_list, my_dict):
    my_list.append(4)  # 向列表中添加一个元素
    my_dict['d'] = 4  # 向字典中添加一个键值对

# 定义列表和字典
original_list = [1, 2, 3]
original_dict = {'a': 1, 'b': 2, 'c': 3}

# 调用函数
modify_data(original_list, original_dict)

# 查看修改后的列表和字典
print(original_list)  # 输出: [1, 2, 3, 4]
print(original_dict)  # 输出: {'a': 1, 'b': 2, 'c': 3, 'd': 4}
