w3schools lists tutorials; half of the functions they use don't seem to work?

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 .

Not Understanding Python Example of Recursion from W3Schools

I am reading that as result = 6+ tri_recursion(6 - 1) Which is correct, but what is happening then? You enter the next recursion depth as tri_recursion(5) which because 5 > 0 calls 5 + tri_recursion(5 -1) Brings us to the next depth level as tri_recursion(4) -> 4 + tri_recursion(4-1) Next level: 3 + tri_recursion(3 - 1) -> 3 + tri_recursion(2) Next: 2 + tri_recursion(2 - 1) -> tri_recursion(1) Next: 1 + tri_recursion(1 - 1) -> tri_recursion(0) For tri_recursion(0)´ the conditionk > 0is no longer satisfied and thus theelsebranch is executed which executesreturn(0)` With this return we move one level back in the recursion to result = 1 + tri_recursion(1 - 1) -> we have the return value from the tri_recursion(1 - 1) call, which is 0 -> so it becomes result = 1 + 0 -> result = 1 The next executed line in the code is print(result) -> which prints the 1 The else´ branch is skipped and the next executed line isreturn resultwhich brings us one level back up to2 + tri_recursion(2 - 1)- the return value from before is1, so it becomes2 + 1->3` which is what is printed. And this goes on until you are back out of all levels. That is what recursion is. More on reddit.com

Shuffling a list

The line in bold is what is giving me an error It's a good idea to post the full error message when asking for help with an error. Besides that i assume you are trying to shuffle a string, you can't do that in python. You need to shuffle a list, and then rejoin it back to a string. pass_list = list(password) random.shuffle(pass_list) password = "".join(pass_list) print(password) More on reddit.com

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

December 19, 2022 - The main characteristics of Python lists are that they are iterable, ordered, indexed, mutable, and allow duplicated values. Place a sequence of items inside square brackets and separate them by comma, e.g., ['cake', 'ice-cream', 'donut']. Alternatively, use the list() built-in function with double brackets: list(('cake', 'ice-cream', 'donut')).
