help with a function

[Lance Hoffmeyer]

Hey all,

I'm new to python.  I keep getting an error when running this.
I'm sure there is an easy fix but I can't figure it out.
What am I doing wrong?  How do I fix it?

def even_odd_round(num):
 	if(round(num,2) + .5 == int(round(num,2)) + 1):
 	     if(int(num,0) % 2):		#an odd number	
 	     	rounded_num = round(num,2) + .1
  	     else:                              #an even number
 	       	rounded_num = round(num,2) - .1
    	rounded_num = int(rounded_num)
    	return rounded_num

even_odd_round(5.5)

Traceback (most recent call last):
