There is no such thing as “raw string” once the string is created in the process. The “” and r”” ways of specifying the string exist only in the source code itself. That means “\x01″ will create a string consisting of one byte 0x01, but r”\x01” will create a string consisting of 4 bytes ‘0x5c’, … Read more
This is a work-around if you are using eclipse. You can automatically have long blocks of text correctly multilined and special characters automatically escaped when you paste text into a string literal “-paste here-“; if you enable that option in window→preferences→java→Editor→Typing→”Escape text when pasting into a string literal”
If you want to use double quotes in strings but not single quotes, you can just use single quotes as the delimiter instead: r’what”ever’ If you need both kinds of quotes in your string, use a triple-quoted string: r”””what”ev’er””” If you want to include both kinds of triple-quoted strings in your string (an extremely unlikely … Read more

To answer your question directly, put r in front of the string. final= path + r’\xulrunner.exe ‘ + path + r’\application.ini’ But a better solution would be os.path.join: final = os.path.join(path, ‘xulrunner.exe’) + ‘ ‘ + \ os.path.join(path, ‘application.ini’) (the backslash there is escaping a newline, but you could put the whole thing on one … Read more
You still need \ to escape ‘ or ” in raw strings, since otherwise the python interpreter doesn’t know where the string stops. In your example, you’re escaping the closing ‘. Otherwise: r’it wouldn\’t be possible to store this string’ r’since it’d produce a syntax error without the escape’ Look at the syntax highlighting to … Read more
First and foremost, replacement patterns ≠ regular expression patterns We use a regex pattern to search for matches, we use replacement patterns to replace matches found with regex. NOTE: The only special character in a substitution pattern is a backslash, \. Only the backslash must be doubled. Replacement pattern syntax in Python The re.sub docs … Read more
Raw string literals are string literals that are designed to make it easier to include nested characters like quotation marks and backslashes that normally have meanings as delimiters and escape sequence starts. They’re useful for, say, encoding text like HTML. For example, contrast “<a href=\”file\”>C:\\Program Files\\</a>” which is a regular string literal, with R”(<a href=”https://stackoverflow.com/questions/56710024/file”>C:\Program … Read more
There’s not really any “raw string“; there are raw string literals, which are exactly the string literals marked by an ‘r’ before the opening quote. A “raw string literal” is a slightly different syntax for a string literal, in which a backslash, \, is taken as meaning “just a backslash” (except when it comes right … Read more
The r means that the string is to be treated as a raw string, which means all escape codes will be ignored. For an example: ‘\n’ will be treated as a newline character, while r’\n’ will be treated as the characters \ followed by n. When an ‘r’ or ‘R’ prefix is present, a character … Read more
