# Python3 最重要的新特性大概要算是对文本和二进制数据作了更为清晰的区分。
# 文本总是Unicode，由str类型表示，二进制数据则由bytes类型表示。
# Python3 不会以任意隐式的方式混用str和bytes，正是这使得两者的区分特别清晰。
# 你不能拼接字符串和字节包，也无法在字节包里搜索字符串（反之亦然）

b = b"example"  # bytes object
s = "example"   # str object

bytes(s, encoding = "utf8")   # str to bytes
str(b, encoding = "utf-8")    # bytes to str
