字符串 字节

 

a. 字符串转字节

1 2	key = "xxxx" bkey = bytes(key,encoding='utf-8')

b. bytearray 数组

1 2 3 4 5 6 7

data = "要加密" ba_data = bytearray(data,encoding="utf-8") print(ba_data)     # bytearray(b'\xe8\xa6\x81\xe5\x8a\xa0\xe5\xaf\x86') print(len(ba_data))     # 9 ba_data.append(11)      #只能追加数字,默认转成字节
