🔒 def with Lists

[viral ivy]

Hi guys is there any way to use the functions with the list so like instead of saying def random(x,y) instead of x,y you put a List??

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

In sounds like you're asking about unpacking

!e

def func(x, y):
    print(f'{x=}, {y=}')

lst = [1, 2]
func(*lst)

x=1, y=2

* "spreads" the iterable into the argument list.

Of course though, you need to be careful to ensure that the length of the list matches the number of parameters the function has, or you'll get an error.

ok thank you

You're welcome.

You can also pass in a list and operate on that from within the function as well

The flip side of this is a function which accepts a variable number of arguments:

def func(*args):
    print(len(args), args)

Usually we prefer the normal function definition with fixed names parameters, but sometimes the variable form is appropriate.
