strings are no different2. Chinese B ' \xc4\xe3\xba\xc3 ' This is a man ' hello ' of Utf-8 's bytes expression formStrings are converted to Bytes->encode (character sets) when they are transmitted.The result after encoding is the same as the source string.The results after the Chinese encoding are different according to the encoding. The encoding results are also different.We know. A Chinese UTF-8 encoding is 3 bytes. The Chinese encoding of a GBK is 2 bytes.The type after encoding is the bytes

(s))How to convert a character to a byte. The byte default is a 16 binary number, which is represented by the 16 binary. One byte equals 8 binary digits.#The S string has four Chinese, which is four characters.

Bytes Type The most important new feature of Python 3 is probably a clearer distinction between text and binary data. Text is always Unicode, represented by the STR type, and binary data is represented by the bytes type. Python 3 does not mix str and bytes in any implicit way, which makes the distinction between them particularly clear. You cannot stitch str
