How to remove a desired part of string? (not using indexes)

Answer 1

If you mean you for example want to subtract " world" from "Hello world!" so that you get "Hello!", you can use the replace method:

Replacing " world" with an empty string:
"Hello world!".replace(" world", "")
---> "Hello!"

Replace method will by default replace all occurences of " world" with the empty string. You can prevent this by adding third argument, which represents how many occurences of " world" you want to replace.

Replacing 2 occurences of " world" with an empty string:
"Hello world world world!".replace(" world", "", 2)
---> "Hello world!"
