Convert Bytes to String Using decode() (Python 2). The total number of characters ASCII can represent is 2=256. Note: Always use an even number of backslashes. However, do you know there are at least four types of strings in primitive Python? Thanks! Here comes my personal suggestions, unless in the scenario where you need to define the regular expression match pattern (See below example), I suggest using the Unicode string with escape (using backslash to ignore special character). For example, to serialize a pandas.Series containing a list of strings with special characters in to a textfile in the format BERT expects with a CR between each sentence and a blank line between each document: This outputs (for the Github CodeSearchNet docstrings for all languages tokenized into sentences): s = "your string"; raw_s = r'{0}'.format(s). Webpython How to convert a raw string into a normal string? WebWhat is difference between input and raw_input in Python? Home > Python > Python String > Convert String to Raw String in Python. if you need to write unicode strings into a file then you have to encode it first and then use it by decoding it. Use replace() method to remove substring from string. But when using a regular expression, we usually need to first define a matched pattern where the Raw string would be recommended. i believe what you're looking for is the str.encode("string-escape") function. For example, if you have a variable that you want to 'raw string': etc.) It is more than enough for 26 English letters plus some commonly-used characters.
