Python common error messages -TypeError -Arg

TypeError: __init__() takes exactly 2 arguments (1 given)
 
import sys
class tables:
   def __init__(self,w):
       ans = self.T0_r(w)
       print "Result = %s" % (ans)
    
    def T0_r(self, w):
       self.tables_ls()
       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 element of the table array by calling class
   y = tables()
main()
 
This will result in error below:
Error

Traceback (most recent call last):
 File "calling_classes.py", line 27, in ?
   main()
 File "calling_classes.py", line 26, in main
   y = tables()
TypeError: __init__() takes exactly 2 arguments (1 given)
 
Issue of above error is in highlighted line in red above. This can be fixed like below. 
 y = tables(0x4)
