Re: [Tutor] create 1000 000 variables

Good. But one VERY important point to note is that that you are not working
with variables here. You are working with members of a class instance.
This is a very different beast. You could just use getattr(), setattr() and
delattr() for these.
But continuing... you might want to think about this in a step back. Each
of the self.hN and self.in_hN have something in common and they all have the
same behavior. That sounds a lot like a job for object oriented
programming, no? We can create a class that look and acts like a list
(like hN), but is only active if we have set it (if in_hN is True).
Actually, because of the structure of the SGML code, BAD CODE1 isn't quite
the bad code, the handle_data code is actually worse. The reason BAD
CODE1 looks bad is not because of your code, but because SGMLParser forces
you to create so many methods in the subclass. There are no start_hN and
end_hN catch-all methods available. For this reason, I made only a minor
change to the start_hN and end_hN methods, but changed the reset and
handle_data methods quite a bit.
class HeaderCapture:
def __init__(self, contents=[]):
self.contents = contents[:] # copy
self.deactivate()
def append(self, item):
# could raise an exception, but for now, ignore
if self.active:
self.contents.append(item)
def __len__(self):
return len(self.contents)
def __getitem__(self, idx):
return self.contents[idx]
def activate(self):
self.active = True
def deactivate(self):
self.active = False
...
class Lister(SGMLParser):
def reset(self):
SGMLParser.reset(self)
self.headers = {
'h1': HeaderCapture(),
'h2': HeaderCapture(),
'h3': HeaderCapture(),
'h4': HeaderCapture(),
'h5': HeaderCapture(),
'h6': HeaderCapture(),
}
def handle_data(self, text):
# only one would be active, but legally, two could
for hc in self.headers.values():
hc.append(text) # if not active, ignore
def start_h1(self, attrs):
self.headers['h1'].activate()
def end_h1(self):
self.headers['h1'].deactivate()
def start_h2(self, attrs):
self.headers['h2'].activate()
def end_h2(self):
self.headers['h2'].deactivate()
def start_h3(self, attrs):
self.headers['h3'].activate()
def end_h3(self):
self.headers['h3'].deactivate()
def start_h4(self, attrs):
self.headers['h4'].activate()
def end_h4(self):
self.headers['h4'].deactivate()
def start_h5(self, attrs):
self.headers['h5'].activate()
def end_h5(self):
self.headers['h5'].deactivate()
def start_h6(self, attrs):
self.headers['h6'].activate()
def end_h6(self):
self.headers['h6'].deactivate()
To continue this, your BAD CODE2 becomes
for tag in 'h1 h2 h3 h4 h5 h6'.split():
Show_step(tag)

Re: [Tutor] create 1000 000 variables

Example: ['var1', 'var2', 'var3'] - list of strings
Do you know about dictionaries yet?
Yes. I know about dictionaries.
Hello,
Can you show us an example of the kind of dictionary usage you've used
before?
I'm skirting really indirectly on this one, because I'm still not sure
where the difficulty is in applying dictionaries to this problem. Just to
hint at this: the dictionary my_vars shown below:
###
my_vars = {}
my_vars['v1'] = 'tesuji'
my_vars['v2'] = ['anti-suji']
my_vars['v3'] = {'atari' : 1 }
###
is one that directs string names 'v1', 'v2', and 'v3' to some arbitrary
values. We can later look things up in the dictionary by providing the
name of the key:
##
print I'm reading James Davies' %s % my_vars['v1']
print I don't yet have %s % my_vars['v2'][0]
print %s! % my_vars['v3'].keys()[0]
##

Re: [Tutor] So close! But ... error: (10054, 'Connection reset by peer')
You are running on a PC, which doesn't have a SMTP server running on it. The default hostname for smtplib.SMTP().connect() is to localhost (your own machine). You will need to find out the hostname of the mail server that your ISP provides. You probably set it when you set up your email (based on a little research, it looks to be
smtp.cox.net). -ArcegeOn 7/16/06, Grady Henry [EMAIL PROTECTED] wrote:
