this question exact duplicate of: understanding python 3 lists printing none value each element 1 answer im studying comprehensions. print(x) part (i think. prints value of x passes 'in' test) why returning list of none afterward? >>> g ['a', 'x', 'p'] >>> [print(x) x in g] x p [none, none, none] #whats this? you use list comprehension print items in list, , list printed. try assigning list variable instead. >>> g ['a', 'x', 'p'] >>> x = [print(x) x in g] x p # now list in x , isnt printed. list still there... >>> print(x) [none, none, none] >>> x [none, none, none]

when using control datagrid, can use type of column: <asp:hyperlinkcolumn datanavigateurlfield="url_doc" datatextfield="des_doc" headertext="document"> <itemstyle horizontalalign="center"></itemstyle> </asp:hyperlinkcolumn> where "url_doc" come stored procedure value: selet '../documentos/' || res.cod_op || '/' || tdo.des_tipo_doc || '/' || '01' || '/' || res.file_name url_doc mytable url_doc stores path of document file, included in sub folder of asp.net project. when click on hyperlinkcolumn, can open document file. now, if try use gridview, can't find column hyperlinkcolumn. when using gridview, tried use hyperlinkfield like: <asp:hyperlinkfield datanavigateurlfields="url_doc&q

look, it´s simple. have gridview populated data database. what want put button in each cell contains specific datum. pls, image below. describes want in vb.net, pls! =) example image thanks much! you going need define button control inside of <columns> section of gridview markup, this: <asp:gridview id="customersgridview" runat="server"> <columns> <asp:boundfield datafield="datecolumn" headertext="date"/> <asp:templatefield> <headertemplate> positive </headertemplate> <itemtemplate> <asp:label id="labelpositive" runat="server" text='<%# eval("positivecolumn")%>' /> <br /> <asp:button id="buttonpositive" runat="server" text="show" /> </itemtemplate>

i'm trying print lines contain, let say, @ least 35 characters, file. how can this? grep not best tool job. you write: grep ................................... filename or use 1 of more sophisticated regular expression features mentioned in other answers (if grep supports them). awk : awk 'length >= 35' filename or perl : perl -e 'print if length >= 35' filename would more appropriate.

sometimes see javascript written argument provided has set value or object methods. take jquery example instance: $(".selector").children().each(function(i) { console.log(i); }); when logging i , value of whatever i in iteration when looking @ selectors children in jquery each method. take node.js example: http.createserver(function(request, response) { response.writehead(200, {"content-type": "text/plain"}); response.write("hello world"); response.end(); }).listen(8888); you can see here request , response being passed , contain own methods can acted on. to me, looks passing function createserver function 2 arguments have methods attached them. my question multipart one: where these arguments come from? if these anon functions, how receive arguments can acted on other functions? how create functions can take own arguments this?? does use power of closures?? to me, looks passing functio
