Iterating over the elements of two 2D lists in python and printing the difference -


i have 2 2d lists:

list1 = [[]] list2 = [[]]

and in loop iterate on bunch of registers , write operations , readback operation , populated lists.

list1.append([regname,writevalue]) list2.append([regname,readvalue])

now want compare these 2 lists make sure readback values registers same ones wrote. doing that:

for (x,i),(y,j) in itertools.izip(list1,list2):     if [x][i] != [y][j]:         print >> myfile, 'mismatch: reg_name = %s, expected_value =0x%x, actual_value =0x%x' % (x,i,j)

this of course wrong , gives me error saying valueerror:need more 0 values unpack.

how compare write , read values same corresponding register name in 2 lists , print mismatches?

1: way start list1 , list2 empty list causing error!

2: not problem!

when fix list assignment code , run it, following error:

traceback (most recent call last):   file "<stdin>", line 2, in <module> indexerror: list index out of range

that because in for loop, making variables x i y j elements in list , trying index them, , can't that. not sure if syntax use okay...the following want:

for x,y in zip(list1,list2):     if x not y:         # want here

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
