That's exactly what I was looking for and I've probably even used it in that way, but when we get stuck or a brain fart, there's Google. This is the syntax that conveys to the Python interpreter to create a raw string. Then, we replace backslash ( \ ) with double backslashes ( \\ ) in the string and now find the length of the update string. See the manual for the details. How do I print in Python 3.3.3 without carriage return? The interpreter does not implement the escape sequence in such strings but rather considers them as normal characters.

So, the input and output are both the same because the backslash character is not escaped. For example: s = '\n' raw_string = repr(s) In this example, we defined a string using r before quotes and assigned it to a variable. I use the following method to convert a python string (str or unicode) into a raw string: def raw_string(s): if isinstance(s, str): s = s.encode('string-escape') elif isinstance(s, unicode): s = s.encode('unicode-escape') return s. Example usage: We are going to cover these topics: To understand the differences between byte string and Unicode string, we first need to know what Encoding and Decoding are.
