Answer 1

Check your duplicate question :P

Answer 2

Assuming you want to print out the list twice in a single list, the code should be:

def my(l):
l = l + l
return l

mylist = [31,24,75]
print(my(mylist))

1. You need a colon (:) when defining functions.
2. Indentations for lines 2 and 3
3. Tell Python what to return (which I assume is l)
4. When returning a value, Python will not print the result. You have to deliberately tell Python to print it. Which, again, I'm assuming you want to print it.

Answer 3

thank you sooo much

Answer 4

def mystery(l):
l = l + l
return()
my list = [ 31,24,75]
mystery (my list)

what will b output for this
