Hello everyone,
I have this part of my code where I am trying to traverse over an image by
running a for loop for both x and y co-ordinate axis. But the loop is
terminating by just reading first pixel. Can think of a reason why this is
happening ?
The code is:

Thanks Gary.
Be clearer about the problem please.
Do you wish to produce a loop that:
On pass 1, each of p,k, and t hold the first item of their respective
lists, and
on pass 2, each of p,k, and t hold the second item of their respective
lists, and
so on
until one (or all) lists

In the following code I have to access pixels in a segmented image through

I have a prog in which a functions returns a dict but when I try to iterate

In that case, Dave's suggestion to read into a list and iterate over
the list is to be strongly considered. But I'm not entirely sure what
your goal is here. Are you trying to make the Cartesian product of the
two files, where you have one line in the output for each possible
pair of matching
Your current logic tries to scan through the first file, and for each line
that has 12 elements, scans through the entire second file. It fails to
actually do it, because you never do a seek on the second file.
Now it appears your requirement is entirely different. I believe you have
two
That's zip not Zip
Have you tried looking at the docs? Or even typing help(zip) at the
python interpreter prompt?
In rough terms, zip takes one element (line) from each of the iterators,
and creates a new list that holds tuples of those elements. If you use it
in this form:
Here I have a code which basically reads a csv file, tries to compare the
last 2 items in each line of the file.
f = open(rZ:\modules\Feature_Vectors_300_Pclass.arff)
for l in f:
sp = l.split(,)
if len(sp) != 11:
print of, l,
else:
#print sp[9], sp[10]
if
at the
end.
To remove those unwanted characters you could use the strip() function.
So your code could be:
if sp[9].strip() == sp[10].strip():
print Same class
else:
print Different class
At least this works for me when I tried it...

You have defined a classification for 8 of the possible colors, leaving
millions of them undefined. If the first time through the loop you
manage to hit one of those undefined ones, you'll have no value for
classification.
In this code :

Explain no use. If you mean you still fail, then what else did you
try? For example, did you try interchanging the two subscripts? I've
suspected all along that the meanings of row and column, x and y, [0]
and [1], height and width are possibly

for i in xrange(-N, N):

I guess I have to use try and except as Chris suggested, this isn't working.
