*(星号)符号在函数参数附近做什么以及如何在其他场景中使用它？

def my_function(*args):
    for arg in args:
        print(arg)

my_function(1, 2, 3)

1
2
3

# 拆包元组
my_tuple = (1, 2, 3)
print(*my_tuple)  # 输出：1 2 3

# 拆包列表
my_list = [4, 5, 6]
print(*my_list)  # 输出：4 5 6

# 合并多个可迭代对象
list1 = [1, 2, 3]
list2 = [4, 5, 6]
merged_list = [*list1, *list2]
print(merged_list)  # 输出：[1, 2, 3, 4, 5, 6]
