problem while going through a tutorial

[Simon Schuster]

I'm new to python, and almost new to programming in general. I'm at
http://www.pasteur.fr/formation/info...thon/ch04.html in that
tutorial, and my 'count' function (if it's called a function?) isn't
working suddenly.

>>x = "fljshfjh"
x

'fljshfjh'

>>count(x, 'h')

Traceback (most recent call last):
File "<stdin>", line 1, in ?
NameError: name 'count' is not defined

I'm not sure what changed, because it used to work. anyhow thanks a lot!

Probably because you omiitted the line

from string import *

However IMHO your use of a tutorial which:

(1) introduces "from some_module import *" as though it is the normal
way of doing things

From chapter 1: """
Some magical stuff, that will be explained later:

>>from string import *

"""

That's *bad* magic
(2) is still using (outdated) functions in the string module instead of
teaching string methods

should be discontinued immediately.

You may wish to have a look at some of the /other/ tutorials mentioned
on this page:

You forgot to import the string module:
from string import *
