1.解包序列字面量(*)
//字符串
def f(a, b):
print(a, b)
c = "12"
f(*c) # 1 2
//列表
def f(a, b):
print(a, b)
c = [1, 2]
f(*c) # 1 2
//元组
def f(a, b):
print(a, b)
c = (1, 2)
f(*c) # 1 2
//范围
def f(a, b):
print(a, b)
c = range(1, 3)
f(*c) # 1 2
2.解包字典字面量(**)
def f(a, b):
print(a, b)
c = {"a": 1, "b": 2}
f(**c) # 1 2
