Python common error messages -TypeError-str conv

TypeError: not all arguments converted during string formatting

In following python code, a bug is intentionally left to generate a Python error message :-
import sys
class tables:
   def __init__(self,w):
       # 2.4 Definitions of tables for the FSM
       ans = self.T0_r(w)
       print "Result =" % (ans)
    def T0_r(self, w):
       self.w = w
       self.s1_t0_r = self.T0[self.w]
       return self.s1_t0_r
    def tables_ls(self):    
        self.T0 = ['0xFF563C6' ,'0x84FF7CF8' ,'0x897788EE' ,'0x8EFB7BF6',
               '0xFE2F2FF ' ,'0xBCAF6BD6' ,'0xAA6F6FDE' ,'0xFFC5C591']

def main ():
   # Read 0 elemant of the table array by calling class
   y = tables(0x4)
Error message from above Python code:-
Traceback (most recent call last):
  File "", line 28, in ?
 File "", line 26, in main
   y = tables(0x4)
 File "", line 12, in __init__
   print "Result =" % (ans)

ypeError: not all arguments

Instead off
print "Result =" % (ans)
print "Result =%s" % (ans)
