1 basic knowledge of Python coding in Python "plaintext" is Unicode type and str, "ciphertext" is another encoding format such as GBK UTF-8latin-1 Wait code: "Clear Text"-"ciphertext". Encode ([target encoding format]) object must be decoded for Unicode type: "Ciphertext"-"Clear Text". Decode ([source code format]) object is of type STR There are three main classes of encoding for Chinese characters in Chinese characters "Li" as an example of a.
