Python中的解包(tuple和dict的解包、*、**)的几种使用方法

example_list = [1, 2, 3]
print(f"{example_list = }")
print(f"{type(example_list) = }")
print("*example_list:", *example_list)
print()

example_tuple = (1, 2, 3)
print(f"{example_list = }")
print(f"{type(example_list) = }")
print("*example_tuple:", *example_list)

example_list = [1, 2, 3]
type(example_list) = <class 'list'>
*example_list: 1 2 3

example_list = [1, 2, 3]
type(example_list) = <class 'list'>
*example_tuple: 1 2 3

tuple = (1, 2, 3)
print("type(*tuple):", type(*tuple))
