python按位操作以及进制转换

a = raw_input()
 
b = raw_input()
 
c1 = int(str(a), 2)#2进制转化为10进制
 
c2 = int(str(b), 2)
 
c = c1 ^ c2#按位异或
 
c = bin(int(str(c), 10))#10进制转换2进制
 
c =str(c)
 
c = c[2:]
 
rr = [];
 
if len(str(a)) != len(c):
 
c = '0' * (len(str(a)) - len(c)) + c
 
for i in range(len(c)):
 
if c[i] =='0':
 
rr.append('1')
 
else:
 
rr.append('0')
 
rr = str(rr)
 
rr = rr.replace('[','')
 
rr = rr.replace(']','')
 
rr = rr.replace(',','')
 
rr = rr.replace('\'','')
 
rr = rr.replace(' ','')
