r/learnpython on Reddit: Using replace() method
February 27, 2024 -
Hi guys, I had a quick question about the exercise I was working on.
For using the replace() method and printing the result, we have to assign it to another variable and print that new variable.
sentence = sentence.replace(‘hey’, ‘hi’) print(sentence)
But for something such as the sort method we don’t need to assign it to a new variable and just use it straight up.
list = […] list.sort() print(list)
Why is it that some methods you need to assign it to a new variable, while others work while not assigning it to a new variable and the original is changed. Thank you.
Sorry about format, I’m on mobile.

Strings are immutable. That is to say, after they've been created they cannot be modified. If you want to change them anyway, you have to make a copy that contains the changes you want. That's what .replace() does; it makes a new string that is a copy of the original with some portions of it replaced. As for why strings are immutable; there's a StackOverflow thread about that subject . On the other hand, lists are mutable (like most things). You can add, delete, modify, and rearrange its contents all you want, without having to create a new list to do it. So instead of creating a new list, .sort() just modifies the list in-place.

Lists are mutable, strings (and ints) are not. Look it up for yourself. It has to do with the way memory is allocated.
