Python list.remove() explained: removing an item by value
на канале: PythonClassroom
You've been adding to lists. This is the other direction, in the browser with nothing to install.
fruits.remove("banana") takes an item out by what it is, not where it is — you say banana, not position two. Printing the list before and after shows what append never has to deal with: cherry, kiwi and mango all shift along one place to close the gap, and the list gets shorter. That's the real difference between the two methods — append only ever makes a list longer with nothing else moving, remove makes it shorter and moves everything after the gap. This is module 8 of the Year 10 course, and it also flags, without demonstrating, why removing items while looping over a list is worth being careful about later.

Teachers — it's real Python running in the browser, so there's nothing to install on school laptops and no IT ticket to raise.
Open a new tab, go to pythonclassroom.io, and try removing the first item instead of the middle one.
