In Python 3 you encode from a utf-8-encoded-string to bytes and decode from bytes to a utf-8-encoded-string (I stress this point because seeing contradictory Python2 code can result in confusion). In python3 we do know, when the codec is called via encode/decode, but the codecs are still generic in principle. Python bytearray() Syntax bytearray([source[, encoding[, errors]]]). Modbus TCP/IP. I like Python 3. To decode Base64 to original data, Python provides the b64decode function of the base64 module. An explicit cast should be used when the user knows what kind of data they have, and what encoding they have / expect, in order to move from QString (Python 3 str, Python 2 unicode) to QByteArray ( Python 3 bytes, Python 2 str) and vice versa. # NB : this is not secure. It is based on the original PyMOTW series, which covered Python 2. encode('TEXT_ENCODING'), since hex is not a text encoding, you should use codecs. Whenever you read a Byte in Python, a string is returned from '\0x00' to '\0xff'. hexdigest returns a HEX string representing the hash, in case you need the sequence of bytes you should use digest instead. Don’t get me wrong, Python 2 will still be around for a while. Python 3 This is a tutorial in Python3, but this chapter of our course is available in a version for Python 2. PyCharm creates files using the IDE encoding defined in the File Encodings page of the Settings dialog, which can be either system default, or the one selected from list of available encodings.
