        print "Enter Binary Number:", 
        bin = input()
        
        while(bin > 0):
           if( (bin % 10) == 1):
              dec += factor
           bin /= 10
           factor = factor * 2
            
        print "The Decimal Number is: ", dec
        
        #sample output
        #Program for Binary to Decimal Conversion
        #Enter Binary Number: 1010
