[FIXED] How to replace / in string using regex?

Issue

I've tested this regex and it finds the / character without issues.

Then why is this statement not replacing that character?

import re

str = 'bla / bla / bla'
str = re.sub(r'/\//g', ' - ', str)

Solution

You must not have tested your regex against Python's engine, for which your syntax is off. The re.sub function does not use delimiters. Use this version:

str = 'bla / bla / bla'
str = re.sub(r'\s+/\s+', ' - ', str)
print(str)  # bla - bla - bla
