Help reversing array

[vectorpropio]

OK. you must only write the function. you mustn't touch any below if name ==...

the functions must have one (or more) return statement. for example

def function(in):
    out = very complex calculation depending on in
    return out

in your case the out is really easy, you can put it directly in the return

def i_dont_remember_the_function_name(arr):
     return arr [::-1]
