hello everybody! i am a newbie programmer wannabe and i am trying to =
learn to=20
program in python by studying joe strout's basic universe simulator. its =
the only
code i've ever seen that does something non-trivial and interesting that =
i think i=20
could actually understand how it works. i have been rewriting it and i'm =
at the
point where i can type look and see whats in a room. next step is to =
move from
one room to another. anyway i have been looking at this code for a while =
and i'm
still mystified by
# declare some constants
the =3D 1
a =3D 2
The =3D 101
A =3D 102
# get name
def GetName(self, article=3D0):
if not article: return self.name
if article=3D=3Dthe:
if hasattr(self,'the'): return self.the + ' ' + self.name
return 'the ' + self.name
if article=3D=3Da:
if hasattr(self,'a'): return self.a + ' ' + self.name
return 'a ' + self.name=20
if article=3D=3DThe:
if hasattr(self,'the'): return cap(self.the) + ' ' + self.name
return 'The ' + self.name
if article=3D=3DA:
if hasattr(self,'A'): return cap(self.a) + ' ' + self.name
return 'A ' + self.name=20
return self.name
why assign different numbers? what does this code do?
for me this is the most opaque part of the program except
for the parser which i'm treating like a black box for now.
anyway sorry i tend to ramble but if someone could comment
on this code i would really appreciate it.=20
