Replace a stand-alone character in a string using .replace (Python)-CodePudding

I have the following string

string = "House or r or place or r or floor or department or r"

I would like to replace stand-alone r characters (meaning any letter r that does NOT form part of a word) with another string, such as True

I have tried something like the following

string_replacement = string.replace("r", "True")
print(string_replacement)

Which outputs the following

House oTrue True oTrue place oTrue True oTrue flooTrue oTrue depaTruetment oTrue True

Instead, what I would like it to output is

House or True or place or True or floor or department or True

Thanks in advance

You can use re.sub() to replace standalone rs. (The \b in the regular expression refers to a word boundary.)

import re
string = "House or r or place or r or floor or department or r"
result = re.sub(r'\br\b', 'True', string)

print(result)

This outputs:

House or True or place or True or floor or department or True

You can try with .replace(' r ', ' True ')
