The logic is quite simple as such. So we look at bash source code (4.4) itself subst.c:9273 case ‘`’: /* Backquoted command substitution. */ { t_index = sindex++; temp = string_extract(string, &sindex, “`”, SX_REQMATCH); /* The test of sindex against t_index is to allow bare instances of ` to pass through, for backwards compatibility. */ … Read more
You can use the string .replace() method along with rawstring. Python 2: >>> print r’pictures\12761_1.jpg’.replace(“\\”, “https://stackoverflow.com/”) pictures/12761_1.jpg Python 3: >>> print(r’pictures\12761_1.jpg’.replace(“\\”, “https://stackoverflow.com/”)) pictures/12761_1.jpg There are two things to notice here: Firstly to read the text as a drawstring by putting r before the string. If you don’t give that, there will be a Unicode error … Read more
There is a table listing all the escape codes and their meanings in the documentation. Escape Sequence Meaning Notes \xhh Character with hex value hh (4,5) Notes: 4. Unlike in Standard C, exactly two hex digits are required. 5. In a string literal, hexadecimal and octal escapes denote the byte with the given value; it … Read more

The compiler is allowed to extend the language as long as the document the change which gcc does in their docs in section 6.21 Slightly Looser Rules for Escaped Newlines. Recently, the preprocessor has relaxed its treatment of escaped newlines. Previously, the newline had to immediately follow a backslash. The current implementation allows whitespace in … Read more
Accrding to: http://www.vias.org/linux-knowhow/bbg_sect_08_02_01.html : -r If this option is given, backslash does not act as an escape character. The backslash is considered to be part of the line. In particular, a backslash-newline pair may not be used as a line continuation. It works on my machine. $ echo ‘\&|’ | while read -r in; do … Read more
Python3: >>> b’\\u201c’.decode(‘unicode_escape’) ‘“’ or >>> ‘\\u201c’.encode().decode(‘unicode_escape’) ‘“’
If you are using a raw-string, then you do not escape backslashes: f(r’E:\dir’) Of course, this problem (and many others like it) can be solved by simply using forwardslashes in paths: f(‘E:/dir’)
When you print a tuple (or a list, or many other kinds of items), the representation (repr()) of the contained items is printed, rather than the string value. For simpler types, the representation is generally what you’d have to type into Python to obtain the value. This allows you to more easily distinguish the items … Read more
Windows is the bastard child of operating systems in this regard, but a lot of APIs will accept forward slashes as well. On Windows, a file path looks like this: C:\Users\jsmith\Documents\file.txt On a Unix-like system (including Mac OS X and Linux), the same path would look like this: /home/jsmith/Documents/file.txt A URL, standardized in RFC 1738, … Read more
