See my post on Mar 2 about "automating assignment of class variables".
I got no answers, maybe I wasn't clear enough ... :(
Seems so - I for example didn't understand it.
I need to define lots of variables. The variable names are often
identical. The problem is that if I put such a code into a function ...
no, I'm not going to pass anything to a function to get it returned back.
I just want to get lots of variables assigned, that all. If I put them
into module, it get's exectued only once unless I do reload. And I'd have
to use: "from some import *", because mainly I'm interrested in assigning
to self: self.x = "blah"
self.y = "uhm"
Okay, I try and guess: From your two posts I infer that you want to set
variables in instances. But you've got lots of these and you don't want to
write code like this:
class Foo:
def __init__(self, a, b, .....):
self.a = a
self.b = b
....
If that is what you want, then this might help you: Put all the values in a
Good guess! ;)
dictionary - like this:
my_vals = {"a": 1, "b" : 2, ....}
There are plenty of other ways to create such a dictionary, but I won't
digress on that here.
Now in your class, you pass than dict to your constructor and then simply
update the instance's __dict__ so that the keys-value-pairs in my_vals
become attributes:
class Foo:
def __init__(self, my_vals):
self.__dict__.update(my_vals)
foo = Foo(my_vals)
print foo.a
-> 1
Hope this helps,
Sure. Thanks! Would you prefer exactly for this method over the method

Am I so deperately fighting the language? No-one here on the list needs to set
hundreds
variables at once somewhere in their code? I still don't get why:
"include somefile.py" would be that non-pythonic so that it's not available, but
I have already two choices how to proceed anyway. Thanks. ;)
Now have to figure out how to assign them easily into the XML tree.
