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

Question

wht will the value of my list
don't bother about indentation

Answer 1

It will remain same because you aren't updating my list

Answer 2

Do:

def mystery(l):
l.append(42)
# no need to use 'return' statement to return nothing
mylist = [31,24,75]
mystery(mylist)
print(mylist)

... will output: [31,24,75,42] as 'mysteriously' expected ;)

Or to add all the list:

def mystery(l):
for v in l:
l.append(v)

Attempting to assign a new value to 'l' variable, destroy the reference toward the array elements, but don't change the elements, so when the function terminate, the new created one is destroy, and the global 'mylist' is still unchanged... Modifying an element of the array inside the function will do the change in the global array reference, and 'append()' function modify also content ( by adding an item ) without creating new copy of the array ^^

And be aware of have same indentation in blocks, and spaces are not allowed in variable names :P

Answer 3

Finally! Same as my answer! :p
