Case-insensitive string comparison without using lower or upper

Question

I am trying to compare two string and ignore case- sensitive but i don't want to use .lower() or .upper(). Is there another way of doing this?

It seems to me to be unreasonable to do lower twice so i'd wanted to know if there is another way — Doron Shevach, Feb 06 '20 at 13:18

example1 = "hello"
example2 = "HeLlo"

if example1.casefold()==example2.casefold():
    #do something

This will work without needing upper() or lower(). Might not work for non-ASCII characters.

This might give different invalid results - `"ß".casefold() == "ss"` – Sayse Feb 06 '20 at 12:56
@Sayse Yes this is assuming ASCII. Does `.lower()` and `.upper()` work well for non-ASCII characters? – Ahmet Feb 06 '20 at 13:04

@Sayse that seems like a valid result? – Masklinn Feb 06 '20 at 13:09
