Is there a way in Python to return a value via an output parameter?

Question

Some languages have the feature to return values using parameters also like C#. Let’s take a look at an example:

class OutClass
{
    static void OutMethod(o         


        

Answer 1

There is no reason to, since Python can return multiple values via a tuple:

def func():
    return 1,2,3

a,b,c = func()

But you can also pass a mutable parameter, and return values via mutation of the object as well:

def func(a):
    a.append(1)
    a.append(2)
    a.append(3)

L=[]
func(L)
print(L)   # [1,2,3]
