What's t supposed to be, what are you initialising self.a as, where is
t generated, what is your expected output? What else is happening to
self.a?
Looks like an indentation error to me.
This kind of output
[[1, 237, 543], [1, 237, 543], [1, 237, 543], [1, 237, 543]]
would only come from
a loop iterating over the command that appends [1,237,543] several times.
I'd check your logic, logical errors are the hardest.
I use that kind of thing often -
i.e.
x=[]
a="Hello 123, How is 456?"
for item in a:
try:
w=(int(item))/1
except TypeError:
continue
x.append(item)
print x
['1','2','3','4','5','6']
But yeah, post up all the relevant code please, just not the bit
that's not breaking. I can't see your loop that's writing the wrong
values, or perhaps self.a is getting reinitialized wrong? If you get
my point.

'There is only one basic human right, and that is to do as you damn well please.
And with it comes the only basic human duty, to take the consequences.
