`JES - Python, Even and Odd

I need to write a program that asks if a random number is even or odd, the user inputs the answer and then the program tells you if it is correct or incorrect. I do not know what to put in ans=raw_input("is" [random number] "Odd or Even?")

this is what i have implemented right now, what do i do to fix it?

def evenOdd():
  num=random.randrange(1,101)
  ans=raw_input("is"+num+"even or odd?")
  if ans % 2 == 0:
    print "correct"
  elif ans % 2 == 1:
    print "incorrect"
