Python Regular Expression String Substitution Questions

Question

I have the text "languageType": "en" , and I want to replace it with en . How do I do it using replace? I've tried this so far so it's not working

lang = s.split(":")[0].replace("[\"']", "", -1).strip()
print(lang)

But I keep getting "en"

Answer 1

The replace method doesn't accept a regular expression, but rather a string. To replace with a regex use re.sub() . See How to input a regex in string.replace?

I've made the same mistake before, myself.
