return doesn't work

Question

in this simple function, return doesn't work:
def test(n)
a=n
return a

test(5)

why?

Answer 1

return cant print a value alone. if you want to print your value you should use print like this:

print(test(5))

Answer 2

thanks, works!!
in many guides it's not reported, why?

Answer 3

i dont know but i can tell you that you can use like this:
x=test(5)
print(x)

Answer 4

can i ask you also how remove a value from a lista?
thanks in advance

Answer 5

I think that you cant remove a value from a list.
if you want to do it you should rewrite it but just all values that you want and if dont rewrite a value it will remove
