Item-by-item list comparison, updating each item with its result (no third list)



The solutions I have found so far in my research on comparing lists of objects have usually generated a new list of objects, say of those items existing in one list, but not in the other. In my case, I want to compare two lists to discover the items whose key exists in one list and not the other (comparing both ways), and for those keys found in both lists, checking whether the value is the same or different.


The object being compared has multiple properites that constitute the key, plus a property that constitutes the value, and finally, an enum property that describes the result of the comparison, e.g., {Equal, NotEqual, NoMatch, NotYetCompared}. So my object mig

How to improve compare of item in sorted List<MyItem> with item before and after current item?
Databases

Does anyone know about a good way to accomplish this task?


Currently i'm doing it more ore less this way, but i'm feeling someway unhappy with this code, unable to say what i could immediately improve.


So if anyone has a smarter way of doing this job i would be happy to know.


private bool Check(List<MyItem> list)
{
bool result = true;
//MyItem implements IComparable<MyItem>
list.Sort();
for (int pos = 0; pos < list.Count - 1; pos++)
{
bool previousCheckOk = true;
if (pos != 0)
{
if (!CheckCo
How to open list item by clicking on item row (instead of selecting item)?

How to open list item (or folder) when user click on item row (not on linktitlenomenu column)?
By default sharepoint select this item and I need select items by clicking on checkbox only and open item otherwise.
I see many different jQuery scripts, but I find only how to get link on item with jQuery:


$(document).ready(function () {
$('.ms-itmhover').each(
function () {
var a = $(this).find("td div[Field=LinkFilename] a")
alert(a.attr('href'));
}
);
});

But I dont't know how to paste this url in row onclick handler.


Create a list of item on a single line, then query list to see if item exists, without receiving unchecked conversion warning in Java
Databases

I want a list of things, and then I want to test the list to see if an item exists:


Here is my example snippet:


String[] handToolArray = {"pliers", "screwdriver", "tape measure"};
List<String> handToolList = new ArrayList<String>( Arrays.asList(handToolArray));
if (handToolList.contains("pliers")){
System.out.println("I have pliers");
} else {
System.out.println("I don't have pliers");
}

In the second line, the Arrays.asList(handToolArray) generates:

Compare item 1 list one to item 1 list 2 then item 2 list 2 and so forth. Can't iterate properly
Databases

I need help with the concept. I'm new to Python.

I know I need a nested for loop, but the lists are two different sizes. I want to loop the .dat file and check if it matches an item in the .csv file. The thing is something like this doesn’t compare very well.

for row in list1:  
    print(row)  
    for row2 in list2:  
        print(row2[1])  
        if row == row2[1]:  
            print(“match”)
        else:
            print(row2[1] + ' ' + row

)

This will spit out output like this:

list1-item1
list2-item1
list2-item1 list1-item1
list2-item2
list2-item2 list1-item1
list2-item3 
list2-item3 list1-item1

I can see it's not iterating properly due to where I placed the prints. I have two CSV files I'm trying to compare (one line delimited ' ' and one comma delimited). I'm trying to find items from list1 that exist in list2, but I can't seem to get it to iterate past the first item in list1? It would be easier if there was an eof in Python. I know I'm making a dumb mistake somewhere, I just can't figure out where.


if next(item) moves to the next item in a list, what is the eqvilant of next next(item) python

heres the code for context.

    def processScores( file, score):
#opens file using with method, reads each line with a for loop. If
content in line
#agrees with parameters in  elif statements, executes code in if
statment. Otherwise, ignores line    

    with open(file,'r') as f:
        for line in f:  #starts for loop for all if statements
            line = line.strip()
            if line.isdigit():
                start = int(line)
                score.initialScore(start)
                print(line)#DEBUG TEST**** #checks if first line is a
number if it is adds it to intial score

            elif len(line) == 0:
                print(line)#DEBUG TEST****
                continue        #if a line has nothing in it. skip it 


            elif line == 'o' or line == 'O':
                amount = next(f)
                print(line)#DEBUG TEST****
                score.updateOne(amount) #if line contains single score
marker, Takes content in next line and
                                        #inserts it into updateOne
            elif line == 'm'or line == 'M':
                scoreList = next(f)
                lst = []
                for item in scoreList:
                    print(line)#DEBUG TEST****
                    lst.append(item)
                    score.updateMany(lst) # if line contains list
score marker, creates scoreList variable and places the next line into
 that variable
                                          # creates lst variable and
sets it to an empty list
                                          # goes through the next line
with the for loop and appends each item in the next line to the empty
list
                                          # then inserts newly
populated lst into updateMany

            elif line == 'X':
                print(line)#DEBUG TEST****
                score.get(self)
                score.average(self) # if line contains terminator
marker. prints total score and the average of the scores.
                                    # because the file was opened with
the 'with' method. the file closes after 

the idea that I am trying to is work with a file that looks like this:

50

O

30

O

40

M

10 20 30

o

5

m

1 2 3

X

if the code sees an 'O' or an 'o' then it needs to take the next line in the code and add it to a running score.. However the next line is a blank space... So I need to skip to the second line after the 'O' or 'o'.

I was thinking of doing an exception for this, but before I go down that road I wanna see if anyone might know of a better way.
