Is there a way to do something equivalent to "import * from self"?
Perhaps I'm doing something wrong, but I'm having a headache
when dealing with class instance data, forgetting to always
put the "self." prefix
For example, in my brain I'm thinking:
optc,args=getop t.getopt(args,c mdopts[cmd][0], cmdopts[cmd][1])
but I'm having to type:
self.optc,self. args=getopt.get opt(self.args,s elf.cmdopts[self.cmd][0],
self.cmdopts[self.cmd][1])
Is there a way to get rid of those the "self." references, or is this
just something I need to get my brain to accept?
Many TIA,
Mark

No.

Yes.
And FWIW, "from somemodule import *" is usually considered bad style.

I would wonder why it is that all of those need to be attributes on self.
Are you sure you aren't storing too many things as attributes?
Trying to guess some context around that code, I would expect something
like:
def docommand(self, cmd, args):
opts, longopts = self.cmdopts[cmd]
optc, args = getopt.getopt(a rgs, opts, longopts)
return self.getAction( cmd)(optc, args)
or in other words a lot fewer uses of self.

The ones without "self." in front of them will die when you leave
the method (e.g. sort of like local variables in a function). If
you want them to be instance attributes the "self." is required.
Now if you use them a lot you can create shortcuts inside the
method. The lack of "self." is how python knows if this is
a temporary local variable (lasts until the method is exited) or
an instance attribute that lasts across methods. Hopefully this
will help.

It's pretty much just something you'll need to get your brain to accept.
You can replace self with something shorter, like s, but that's sure to
cause mass confusion for other people who try to read your code.
I, however, find that the self. references are a great benefit to
readability, as it makes the scope of a variable quite easy to tell. A
lot of my C++ code is littered with `this->' or similar
explicit-scope-description things...

Hello,
I'm a newbie Python user, a systems administrator - I've been trying

I cannot understand so far is why I need the special 'self' (or anything

explanation in the docs, a quick Google search did not help. Is there
somewhere on the web you could direct me to?
Thanks,

Normally, I expect a subclass to act in a manner consistent
with its Base classes. In particular, I don't expect to

One (common?) exception seems to occur in initialization. I

when calling a object in an html, should I use self.objectname
this.objectname or document.objectname?
for example, i have a form called theform and a link called thelink
i can call
document.theform, but not document.thelink
i can use both this.theform and this.thelink and self.theform and
self.thelink.

The Python FAQ 1.4.5 gives 3 reasons for explicit self (condensed version):
1. Instance variables can be easily distinguished from local variables.
2. A method from a particular class can be called as
baseclass.methodname(self, <argument list>).
3. No need for declarations to disambiguate assignments to local/instance
variables.

HI
I'm currently using Python. I find that a instance variable must
confined with self,
for example:

def __init__(self):
self.aa=10
def bb(self):
print self.aa # See .if in c++,I could use aa to change that
variable

Is there any trick to get rid of having to type the annoying,
character-eating "self." prefix everywhere in a class? Sometimes I
avoid OO just not to deal with its verbosity. In fact, I try to use
Ruby anywhere speed is not crucial especially for @ prefix is better-
looking than self.
But things grow -- is there any metaprogramming tricks or whatnot we
can throw on the self?
