I want to compare two binary files and see if they are the same.
I see the filecmp.cmp function but I don't get a warm fuzzy feeling
that it is doing a byte by byte comparison of two files to see if they
are they same.
What should I be using if not filecmp.cmp?

I'm really worried that python may is doing some things I wasn't
expecting... but lets see...
if I pass a list to a function def fn(myList):
and in that function I modify an element in the list, then does the
callers list get modied as well.
def fn(list):
list[1] = 0
myList = [1, 2, 3]

Is there a way to calculate the mean and standard deviation on array

Do I need to import it into a Numeric Array to do this?

I have a list and I need to do a custom sort on it...
for example:
a = [1,2,3,4,5,6,7,8,9,10] #Although not necessarily in order
def cmp(i,j): #to be defined in this thread.
a.sort(cmp)
print a
[1,4,7,10, 2,5,8, 3,6,9]
So withouth making this into an IQ test.
Its more like
1 4 7 10
2 5 8
3 6

If you are deriving a new class from another class,
that you must (I assume) know the initializer of the other class.
So in myClass
import array
class myClass(arrary.array):
def __init__(self, now here I need to put array's constructor
parameters..., then mine):
array.array.__init__(self

Hi I am using arrays in an application.
They have been working very well for me as I have been using them for
reading and writing data to and from files whose endianisms can be big
or little endian.
However now I need handle data that can be transferred over a socket.
I would rather not have to go

So
Basically I think the problem is in converting from a 32 bit integer to
a 16 bit integer.
I have two arrays:
import array
a = array.array('L', [65537])
b = array.array('H', [0])
b[0] = a[0]
Which gives an overflow message
So can't I truncate the long by discaring the upper bits ..
Like b[0
f = open('myfile.bin', 'rb')
How do I know if there was an error opening my file?
