To me it seems like "the r'' operator" and .encode() are not the same. Understanding the conversion is very important because sometimes the standard output from other programs will be in the format of bytes, and we need to first decode them to Unicode string for further Streaming operation. Declare substring to remove it from my_string. In Python, characters that cannot be represented in a normal string (such as tabs, line feeds. These three: '\bla\ \n' --- r'\bla\ \n' --- ('\bla\ \n').encode("unicode_escape").decode() all give different strings it seems: '\x08la\\ \n' --- '\\bla\\ \\n' --- '\\x08la\\\\ \\n', In case it also helps someone else, I also needed the additional, +1 for the rare, accurate usage of "it is what it is". Python2 IndexError Python Python .values[0] Python-float How do I make the first letter of a string uppercase in JavaScript? But again, the code point still can not be recognized by the computer, so we have UTF-8 or other variants encoding schema to convert the code point to the byte. the, Those extra replaces slash are not needed after.
