extract

I want to extract data from an array (original array with key and value). After I extract the array, I want two new arrays, the first one with just the keys, the second one with just the values, and both without indexes (see code example). // original array $array = array( "name1"=>500 ,"name2"=>400 ,"name3"=>300 ,"name4"=>200 ,"name5"=>100 ); // after extraction $array1 = array('name1','name2','name3','name4','name5'); $array2 = array(500,400,300,200,100); // not like this // $array1 = array(0=>'name1',1=>'name2',2=>'name3',3=>'name4',4=>'name5); // $array2 = array(0=>500,1=>400,2=?300,3=>200

I have a small problem with something I need to do in school... My task is the get a raw input string from a user ( text = raw_input() ) and I need to print the first and final words of that string. Can someone help me with that? I have been looking for an answer all day... You have to firstly convert the string to list of words using str.split and then you may access it like: >>> my_str = "Hello SO user, How are you" >>> word_list = my_str.split() # list of words # first word v v last word >>> word_list[0], word_list[-1] ('Hello', 'you') From Python 3.x , you may simply do: >>> first, *middle

I want to select all comments from a document using JSoup. I would like to do something like this: for(Element e : doc.select("comment")) { System.out.println(e); } I have tried this: for (Element e : doc.getAllElements()) { if (e instanceof Comment) { } } But the following error occurs in eclipse "Incompatible conditional operand types Element and Comment". Cheers, Pete Since Comment extends Node you need to apply instanceof to the node objects, not the elements, like this: for(Element e : doc.getAllElements()){ for(Node n: e.childNodes()){ if(n instanceof Comment){ System.out.println(n); } }

I've got a pretty big comma-delimited CSV log file (>50000 rows, let's call it file1.csv) that looks something like this: field1,field2,MM-DD-YY HH:MM:SS,field4,field5... ... field1,field2,07-29-10 08:04:22.7,field4,field5... field1,field2,07-29-10 08:04:24.7,field4,field5... field1,field2,07-29-10 08:04:26.7,field4,field5... field1,field2,07-29-10 08:04:28.7,field4,field5... field1,field2,07-29-10 08:04:30.7,field4,field5... ...
