Question

I need to do this:

text = re.sub(r'\]\n', r']', text)

But with find and replace as variables:

find = '\]\n'
replace = ']'
text = re.sub(find, replace, text)

Where should I put r (raw)? It is not a string.

Answer 1

The r'' is part of the string literal syntax:

find = r'\]\n'
replace = r']'
text = re.sub(find, replace, text)

The syntax is in no way specific to the re module. However, specifying regular expressions is one of the main use cases for raw strings.
