What is wrong with this code?

Question

I am testing out regex to replace a list of numbers I don't know if it has ever been done before so.

I want to replace 3 in the list with 11
And 4 in the list with 12
Using regex

Is there any way to do this?

import re

list = [3,4]

newlist = [re.sub(r/d/3, 11, list)]
print(newlist)

Answer 1

Regex is used to edit strings. It’s not designed to edit integer data or other data types. If you had a string like “I have 3 apples.” You could replace the 3 with 11 in that string.
