Python: Can a function return an array and a variable?

Your function is correct. When you write return my_array,my_variable, your function is actually returning a tuple (my_array, my_variable).

You can first assign the return value of my_function() to a variable, which would be this tuple I describe:

result = my_function()

Next, since you know how many items are in the tuple ahead of time, you can unpack the tuple into two distinct values:

result_array, result_variable = result

Or you can do it in one line:

result_array, result_variable = my_function()

Other notes related to returning tuples, and tuple unpacking:

I sometimes keep the two steps separate, if my function can return None in a non-exceptional failure or empty case:

result = my_function()
if result == None:
    print No results
    return
a,b = result
# ...

Instead of unpacking, alternatively you can access specified items from the tuple, using their index:

result = my_function()
result_array = result[0]
result_variable = result[1]

If for whatever reason you have a 1-item tuple:

return (my_variable,)

You can unpack it with the same (slightly awkward) one-comma syntax:

my_variable, = my_function()

Its not ignoring the values returned, you arent assigning them to variables.

my_array, my_variable = my_function()
