Python函数指定参数、返回值类型

def fun(arg1: str, arg2: int ...) -> str:

def as_view(name: str, *class_args: int, **class_kwargs: str) -> int:
    return int(name) + class_args[1] + int(class_kwargs['k1'])

print(as_view('1', 2, 3, 4, k1='5', k2='6'))

print(type(as_view('1', 2, 3, 4, k1='5', k2='6')))

print(str(as_view('1', 2, 3, 4, k1='5', k2='6')))

print(type(str(as_view('1', 2, 3, 4, k1='5', k2='6'))))
