Passing multiple arguments to a function?

Question

I am trying to do an operation like the one below:

a = 2
b = 4
c = 6

def my_function(a,b,c):
    a1 = a*2
    b1 = b*2
    c1 = c*2
    return (a1,b1,c1)

x = my_function(a,b,c)

my_function(x)

Where I would like to call my_function() iteratively on its own output if it meets a certain condition.

However, I get the result:

TypeError: my_function() missing 2 required positional arguments: 'b' and 'c'

I am sure this is a basic question and has been answered elsewhere, but it seems so simple that it is difficult to search for.

Answer 1

使用*来解包元组，以便它的所有元素都可以作为不同的参数传递。

my_function(*x)

Answer 2

Use the "star args" syntax.

my_function(*x)
