Hi,
Can some one give, or point to some good examples of how @decorators work, and
__call__ (able) objects? I'm having trouble getting my head around these
techniques (concepts).
Cheers,
T

Hi,
i want to ask one thing that suppose i have a .txt file having content
like:---
47 8 ALA H H 7.85 0.02 1
48 8 ALA HAH 2.98 0.02 1
49 8 ALA HBH 1.05 0.02 1
50 8 ALA C C179.39 0.
one way is:
import re
infile = open("test.txt", "r") #: open read mode
outfile = open("out.tx", "w") #: open write mode
for line in infile:
values = re.split("\s+", line) # split values on spaces EX: ['47', '8',
'ALA', 'H', 'H', '7.85', '0.02', '1']
outfile.write("%s %s C = %s CA = %
I guess I have to start somewhere to ask
I want the user to input a name, say "Chris". I know I can use the code:
name=raw_input()
I now want:
"Chris"=zeros((3,3))
so that when I type:
print Chris
the return will be an array of zero's 3x3
So that I can understand this deeper, I

Yeah, I figured that. I got it to work thanks, but I still don't
understand how exactly. Coming from Perl I am used to a more procedural
type of programming. BTW - Selenium is a great tool for web testing, and
the way it will translate your web clickstream into your choice of
languages rocks.

This is a FAQ. In Python one is discouraged from dynamically creating
variable names. Preferred
not sure exactly why you would want to that, but you could assign attributes
to a class
EX:
class storage:
pass
>> store = Storage()
>> name=raw_input()
>> setattr(store, name, zeros(3,3))
>> print store.Chris

I have a few problems. I know how to convert the lines into an integer but I
don't know how to iterate through all the lines and just get the integers
and
i have a duel loop that looks like thiswhile y > 0 and x > 0:
i cant figure out if there is a way to make so if one loop ends it says
something different than if the other loop ends.

You could use the int() function to try to convert a line to an integer,
and if that fails with a ValueError ex

Maybe you could use two separate tests and break out of the loop if x or
y gets too low.
Because the tests are separated you could say something diff

I have another question about writing the xml tree to a file.
Now, I have parsed and changed my xml tree, but I want to create the same
tree multiple times with different values and write it to one file.
Let's use this code:

Thanks guys,
In the example the __call__ method has *args and **kws as arguments. Is that
required?
Also when, in what situation would you use callable objects?

no the __call__ function can is like any function
def __call__(self, passedin):
or simply
def __call__(self)
