How can I use the ".find" and ".append" functions? It seems like online python doesn´t recognise them

Question

I'm trying to solve some school homeworks and we´re studying the programmer functions and I need to use these both and no matter what when I run the programm there´s an error label, and the fuctions don´t change their color in the code like the other ones

Answer 1

I'm not sure what classes you are using these methods on, so I'll give generic answers. For .find(), if you use it on a string, it will look something like this:

---

myStr = "This is a string"

print(myStr.find("i"))

output:

2

This is because the first appearance of the string "i" is at index 2. 

For lists, there is a .append() method used as follow:

myList = [1,"a","b",2]

print(myList)

myList.append("c")

print(myList)

output:

[1, 'a', 'b', 2] <-- before append
[1, 'a', 'b', 2, 'c'] <-- after append

where the argument inside the .append method is the item which you're appending to the list.
