October 2, 2023 -

Total newbie here. Just been doing some basic exercises and I think the site I'm using is missing some advice, but its such a basic problem I've had no luck googling.

https://www.w3schools.com/python/python_lists.asp

Here they have a list of functions for working with lists; "index()"; "count()"; etc. and implies that these are "built in". However my Python install (3.11.5) doesn't have them as core. I assume I just need to import a module but w3 doesn't tell me which module to import.

Am I right? If so which module is it? I assume its really basic common knowledge.

Thanks x

The index(), count() and other "functions" you mention aren't standalone functions, they are methods of lists. That means you apply them to the list, like this: test = [1, 2, 3, 4, 5, 6] print(test.index(3)) # print index in list of the element of value 3 The list methods are described in the documentation .

Can you mention explicitly what you've done and how Python reacts? I have 3.11.5, and the builtin list functions you've mentioned work just fine. >>> b = ['apple', 'banana', 'apple', 'cherry'] >>> b.count('apple') 2 >>> b.index('banana') 1
