[Tutor] if statement problems(noob question)

[Max Smith]

Hi, everyone whom might read this, im Max and i am really new to coding,
been going at it for about two weeks using codeacademy and the book "think
python".
when i decided to experiment a little with if statements i ran into the
following problem:

def plus(x,y):
    if x and y == int or float:
        print "The answer is: " + str(x+y)

    else:
        print "not a number"


plus(2,2)
plus("one","two")

concatenates one and two insted of printing "not a number"

i have tried to simplify by not cheacking for float values an i have also
tried.

def plus(x,y):
    if x and y == int or float:
        print "The answer is: " + str(x+y)

    elif x or y != int or float:
        print "not a number"

Am i perhaps missing something with the logic gates?

Any help is greatly appreciated !
