Delete some text from current URL using selenium? [duplicate]

I have an url, let's say it is:

website.com/sometext/someothertext/deletetext

How do I delete deletetext? Then add some other text e.g: 123456? Preferably using selenium. I'm only trying to delete the text after the 3rd / I don't want to delete any text before that.

So far I've just got the current url (not including all the other code that doesn't matter here)

current_url = driver.current_url

I found the solution:

current_url = driver.current_url
new_url = current_url.replace("deletetext", "123456")
driver.get(new_url)
