從變量設置* args？

Question

是否可以從一個變量中設置*args？

def fn(x, *args): 
    # ... 

# pass arguments not as list but each as single argument 
arguments = ??? # i.e.: ['a', 'b'] 


fn(1, arguments) 

# should be equivalent to 
fn(1, 'a', 'b') 

Answer 1

是的，你可以使用參數拆包（也被稱爲潑灑）：

fn(1, *arguments) 

下面是一個演示：

>>> def fn(x, *args): 
...  return args 
... 
>>> arguments = ['a', 'b'] 
>>> fn(1, *arguments) 
('a', 'b') 
>>> 

Answer 2

# pass arguments not as list but each as single argument 
arguments = ??? # i.e.: ['a', 'b'] 

然後參數應分配arguments = ['a' ,'b']。這是論據拆包。
