Integer From A Float List?!?

Hello NG,

I was wondering if there is a way to obtain, from a list of floats,
a list of integers without loops. Probably is a basic question, but I can't
find an answer... I have had my eyes blinded by Matlab for years, but now
that I discovered Python+wxPython there seems to be no limit on what one
can do with these 2 tools. Anyway, following the Matlab style, I would like
to do something like this:

matrix = [1.5, 4.3, 5.5]
integer_matrix = int(matrix) (float for Matlab)

(In Matlab, "integer_matrix " is always a double anyway, here I would like
only to show the vector-matrix operation).

Obviously, Python complains about:

Traceback (most recent call last):
File "<interacti ve input>", line 1, in ?
TypeError: int() argument must be a string or a number

I would like to avoid loops because, having been blinded by Matlab vector-matrix
abilities (and corresponding SLOW for-while loops operations), I tend to
think that also Python will be slow if I use loops.

Does anyone have a suggestion (or maybe could anyone show me that I'm wrong
about loops?)

Thanks you a lot.

Andrea.

I'm pulling a range of cells from Excel into a list and the data in Excel is a number or possibly some text like an asterisk. Each member of the list is a com object (I think) and I'm converting them to integers (or to None if not numberic) but my method seems very silly. Is this the best way to go about it? It does exactly what it...

Greetings, I have a question about parsing a fixed-width integer from a string. Lines of data are being read from a file having a very strict column-delimited format. In my example below, columns 0-7 are an integer and columns 8-23 are a float. In _most_ files, the first few columns of the float are blank space to make it human...

Suppose that I have an integer division problem, but I want the answer was a float. What's the cleanest syntax for that? Example: In this code, the variable z ends up == 0. And that is correct, because this is integer division and the values are trunc'd. No problem. But what's the most elegant code given that x and y have to be ints,...
