Be clearer about the problem please.<br>
<br>
Do you wish to produce a loop that:<br>
On pass 1, each of p,k, and t hold the first item of their
respective lists, and<br>
on pass 2, each of p,k, and t hold the second item of their
respective lists, and<br>
so on<br>
until one (or all) lists run out?<br></div></blockquote><div><br></div><div style>Yes this is excatly what I want each loop holds the first item on each pass. </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<br>
If that is what you want, then check out the zip builtin function.
But also consider this: Do you care what happens if one list runs
out before the others? <br></div></blockquote><div><br></div><div style>Yes, but all dictionaries have same number of items. </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<div bgcolor="#FFFFFF" text="#000000">
<br>
Or is it something else you want? Perhaps nested loops?<br>
for p in sorted(segments.iterkeys()):<br>
for k in sorted(class_count.iterkeys()):<br>
for j in sorted(pixel_count.iterkeys()):<br>
# This will be run with all possible combinations of
p,k, and t</div></blockquote><div><br></div><div style>No, I know about nested loops but I dont want that because all the loops have same number of items, inner loops will run out earlier. </div><div style> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
