user input and lists

23
Hi, Python is the first language for me to get into. I'm still really new and have a lot to learn, though...

Does anyone know how to allow users to append lists?

I tried

user.append = raw_input("Type in desired username ")

But apparently .append is read only. D:

you can't do that.

users = []
user = raw_input( "Enter user:")
users.append(user)

Oh....Duh, nvm.

I've run into another problem, but from what I've seen, the proper sintax is

user.append(raw_input("Type in desired username "))

right?

I can't properly test it, because (after changing user to a list) my original code directly afterward doesn't work.

if len(user) > 4:

Doesn't work because it's asking how many objects are in the list. D:

I tried

if len(user[0]), too, but to no avail. I think I've discovered a better way to do what I want, so I'm going to revert to user being a simple string, but I'd still like to know.


EDIT: Oh, ok.

it should be users.append(raw_input("Type in desired username "))
if you declared "users" as a list

len(users) will show how many items are inside the list

I know, but the intention was to find the number of characters in a particular object in the list. A 'no less than five characters' thing.

I don't really need it anymore because I'm changing the way I'm going about this particular problem, but is it possible to do that using the len function on lists?




Thanks for the help, mate.
