The \b is a back space character

If you want to print the string \foo\bar do this:
>>> print r"\foo\bar"
\foo\bar
This utilizes the raw strings available in python.
String literals may optionally be prefixed with a letter 'r' or 'R'; such strings are called raw strings and use different rules for interpreting backslash escape sequences

r/Python on Reddit: What is \b realistically used for?
December 23, 2021 -
Hi all,
Does anyone know what \b is used for in python? I get that it does a backspace in a string, but why would you want to do that? I've tried looking online and can't find any realistic examples of why it would be used.
Many thanks in advance :)

The other time you might want to use it is if say you had a string which said "loading..." and then had say a percentage or a "text spinner" at the end (i.e. loops through | / - \ |). You can print the \b character however many times required to only update that bit of text on the screen, eliminating (or at least vastly reducing) flickering/refreshing/repetition of text. from time import sleep s="|/-\\" print("Loading....", end="", flush=True) for i in range(20): print(f"\b{s[i%len(s)]}", end="", flush=True) sleep(0.5) (Edit) included flush=True as per suggestions.

You could algorithmically use the \b to do something. Say you make your own text editor, you might want to use \b to do backspaces so you can keep track of changes made. So during a ctrl-z you could get rid of the backspaces. I will say, this was just thought of off the top of my head. But it’s the only real use case I could see.
Slash vs backslash to separate folders
but whenever I copy a file address in Windows it copies with the folders separated by backslashes You should use an appropriate type for file paths, such as pathlib or os.path (low level), which handles the directory separators for you. https://docs.python.org/3/library/pathlib.html More on reddit.com

That's because just typing x doesn't show you the string.

August 12, 2021 - Because those \b represent an escape sequence, they don't end up giving us any matches. Whenever I'm making a regular expression in Python, I always prefix it with an r (just in case). Raw strings are a way of making a string in Python that has no escape sequences and instead reads every backslash as a literal backslash.

Note: you need to be careful when implementing this in Python. \b is actually the backspace character. So you will have to escape the backslash by using \\b instead, i.e. "\\bred\\b". Alternatively and preferably, use a Python raw string literal: r"\b" is equivalent to "\\b".
