I am creating a terminal based python application whereby the user drags and drops a csv file into the terminal to get the file path. The file path is therefore escaped.

How do I remove all instances of this?

For example, I have a file

thisisatestfile/\(2).csv

but when I drag it into terminal it appears as:

thisisatestfile\:\\\(2\).csv

I have a list of all the shell escape characters that I need to remove: link to characters

I am not very good at regex so any help much appreciated!

Maybe you should use the [`shlex`](https://docs.python.org/2/library/shlex.html) module to parse the input. – Barmar Oct 16 '19 at 18:38
forgot to say, must work on 2.7.10 – Itergator Oct 16 '19 at 18:40
Create a dictionary that maps each of the escape sequences to the corresponding replacement. Then use `re.sub()` to replace them all. – Barmar Oct 16 '19 at 18:42
@Barmar you can use the shlex library in python 2.7.10 therefore am using this. Thank you for your help. – Itergator Oct 16 '19 at 19:10
