Python里面怎么改变unicode编码，如把b\\u1234和b\\u1111加起来变成b\\u2345?

python里面怎么改变unicode里面数值的内容，有啥函数吗

给你个例子：
x = b'\\u1234'
y = b'\\u1111'

xx = bytearray(x)
yy = bytearray(y)
print( xx, yy)
xx[2] = 97 #字符a的ascii

print(xx, xx.decode())
上面是改某个字节


x = b'\\u1234'
y = b'\\u1111'
xx , yy = x.decode(), y.decode()
res = int(xx[2:]) + int(yy[2:])
res = r"\u" + str(res)
print(res.encode())
