i'm wondering if possible convert date show oct 31 00:00:00 2013 gmt 10-31-2013 . i'm getting date follow: notbeforedate=$(openssl x509 -noout -in ${certificate} -dates | grep "notbefore") the date i'm getting oct 31 00:00:00 2013 gmt , wanted convert 10-31-2013 . there's command that? or have manually? if so, best way create own function , send long date parameter , return short date. the openssl command make notbeforedate variable have value (at least in bash version i'm using): notbefore=oct 31 00:00:00 2013 gmt so, first need remove notbefore= part: datestr=${notbeforedate/notbefore=/} then can use date command: date --date="$datestr" --utc +"%m-%d-%y" the --date option tells command use datestr value, --utc tells date in utc (as specified gmt part) , +"%m-%d-%y" formats date desired format. the output is: 10-31-2013 ps: options can vary according linux version. ca...

say have these lists: a = [1, 2, 3, 4] b = [6,7] c = ['a', 'b', 'c'] i create 3-dimensional data structure contains new lists combining elements of each list in possible ways. access these new list using matrix indexing. so example, f function want. this: m = f(a,b,c) then m[0][0][0] give [1,6,'a'], m[1][0][0] give [2,6,'a'], , on. basically, know can using nested loops. jlist = [] j in a: klist = [] k in b: llist = [] l in c: o = [j,k,l] llist.append(o) klist.append(llist) jlist.append(klist) this gives me list of lists of lists of lists. [[[[1, 6, 'a'], [1, 6, 'b'], [1, 6, 'c']], [[1, 7, 'a'], [1, 7, 'b'], [1, 7, 'c']]], [[[2, 6, 'a'], [2, 6, 'b'], [2, 6, 'c']], [[2, 7, 'a'], [2, 7, 'b'], [2, 7, 'c']]], [[[3, 6, 'a'], [3, 6, 'b'], [3, 6, 'c...

okay fooling around making random programs , seeing outputs understanding how things work , noticed strange thing integer/float arrays. unlike char array '\0' character not stored directly after last entered element array. in integer array stored 2 elements after last element , in float 4 elements. here's code demonstrate strange fact. please me understand why happens. #include <stdio.h> #include <string.h> void foo(int* x) { while ( *(x) != '\0' ) { printf("%i ",*x); ++x; } } void foo1(float* x) { while ( *(x) != '\0') { printf("%.1f ",*x); ++x; } } void foo2(char* x) { while( *(x) != '\0' ) { printf("%c",*x); ++x; } } int main(void) { int a[4] = {1,2,3,4}; float b[4] = {1.1,2.2,3.3,4.4}; char name[] = "muneeb"; foo(a); printf("\n\n"); foo1(b); printf("\n\n...

i have activity sends boolean array inventory class maingame activity. when onacivityresult runs resultcode 0 , data null. starting inventory activity: @requiresapi(api = build.version_codes.jelly_bean) public void openinventory(view v) { intent bag = new intent(maingame.this, inventory.class); bag.putextra(booinventory, inventory); startactivityforresult(bag, requestitem); } ending inventory activity: public void onpause(){ intent item = new intent(inventory.this, maingame.class);//data sent maingame activity item.putextra(tools, itemused); setresult(result_ok, item); super.onpause(); } onactivityresult: (toaster method creates toast) @override public void onactivityresult(int requestcode, int resultcode, intent data) { super.onactivityresult(requestcode, resultcode, data); if(requestcode == 2){ if(resultcode == result_ok){ toaster("result ok",...

this problem i've been trying deal hour now, figured might ask question. goal/question behaviour of list supplied pane.getchildren(). explain better, here's bit of example code. vbox pane1 = new vbox(); label label1 = new label("a"); label label2 = new label("b"); pane1.getchildren().addall(label1,label2); system.out.println(pane1.getchildren().size()); (int i=0; i<pane1.getchildren().size(); i++) { system.out.println(i + pane1.getchildren().get(i).(??????????) } the list pane1.getchildren() of size 2, pane1.getchildren().get(i) doesn't allow me use label related methods (such gettext(), 1 i'm interested in accessing). happening here, why isn't pane1.getchildren().get(i) acknowledged label? also worth adding, if run for (int i=0; i<pane1.getchildren().size(); i++) { system.out.println(i + pane1.getchildren().get(i).getclass().getname()); } the console output says, name of class "javafx.scene.control.label". ...

i break down pandas column consisting of list of elements many columns there unique elements i.e. one-hot-encode them (with value 1 representing given element existing in row , 0 in case of absence). for example, taking dataframe df col1 col2 col3 c 33 [apple, orange, banana] 2.5 [apple, grape] b 42 [banana] i convert to: df col1 col2 apple orange banana grape c 33 1 1 1 0 2.5 1 0 0 1 b 42 0 0 1 0 how can use pandas/sklearn achieve this? we can use sklearn.preprocessing.multilabelbinarizer : from sklearn.preprocessing import multilabelbinarizer mlb = multilabelbinarizer() df = df.join(pd.dataframe(mlb.fit_transform(df.pop('col3')), columns=mlb.classes_, index=df.index)) result: in [77]: df out[77]: col1 col2 apple banana grape orange 0 c 33.0 ...
