I see that they produce the same result, is the difference in speed? Why are there 2 functions for the same thing?

> range(5)
[0, 1, 2, 3, 4]
>>> xrange(5)
xrange(5)
>>> for i in range(5):
...     print i
... 
0
1
2
3
4
>>> for i in xrange(5):
...     print i

I need to call an executable that is in the same directory as a running python script . I need to know how I can call it through a command from my script with some parameters.

In the Windows command line, I do this:

miejecutable -p1 datos

Preferably if there is a way to run it in both Python 2 and 3.

Situation

When executing the following queries, the same number of records is obtained, I would like to know what is the difference of using a (+)at the end of the query.

SELECT A.IDTABLAA,B.NOMBRETABLAB
FROM TABLA_A A, TABLA_B B
WHERE A.IDTABLAA=B.IDTABLAB

--Record Count: 2,265

SELECT A.IDTABLAA, B.NOMBRETABLAB
FROM TABLA_A A, TABLA_B B
WHERE A.IDTABLAA=B.IDTABLAB(+)

--Record Count: 2,265

Environment

• Database: Oracle 11g

The title is explicit. What fundamental or fundamental difference is there between these methods when defining the functions or methods?

Important: Despite being a very similar question to this one on stackoverflow , it is not intended to be a translation of any of their answers.

I am developing an Android application that contains a dynamically generated menu, so the menu is generated by programming:

private void cargarAvisosMenu() 
{
    // Menu
    final Menu menu = this.mNavigationView.getMenu();


    // Carga de datos
    CentroSelection selection = new CentroSelection();
    CentroCursor cur = selection.query(getApplicationContext().getContentResolver());

    // Recorro el cursor de centros
    while (cur.moveToNext()) {
        boolean avisosTipoA = false;
        boolean avisosTipoB = false;

        Centro c = Centro.getFromCursor(cur);
        if (c.getIsTipoAVisible() && c.getComponenteTipoA().getControlesTipoAPendientes() > 0) {
            avisosTipoA = true;
        }
        if (c.getIsTipoBVisible() && c.getComponenteTipoB().getControlesTipoBPendientes() > 0){
            avisosTipoB = true;
        }

        if (avisosTipoA || avisosTipoB) {
            // Añado la sección y los items.
            final SubMenu subMenu = menu.addSubMenu(c.getNombre());
            if (avisosTipoA) {
                subMenu.add("TipoA").setIcon(R.drawable.ic_tipoA);
            }
            if (avisosTipoB) {
                subMenu.add("TipoB").setIcon(R.drawable.ic_tipoB);
            }
        }
    }
}

My intention is to add a counter indicating the number of notifications (gmail style).

According to the documentation this is possible, either through an xml menu, using the attribute app:actionLayout, or using the function MenuItemCompat.setActionView(). Since the menu that I am developing is dynamic, I have opted for the second option, so that the code would be as follows:

private void cargarAvisosMenu() 
{
    // Menu
    final Menu menu = this.mNavigationView.getMenu();


    // Carga de datos
    CentroSelection selection = new CentroSelection();
    CentroCursor cur = selection.query(getApplicationContext().getContentResolver());

    // Recorro el cursor de centros
    while (cur.moveToNext()) {
        boolean avisosTipoA = false;
        boolean avisosTipoB = false;

        Centro c = Centro.getFromCursor(cur);
        if (c.getIsTipoAVisible() && c.getComponenteTipoA().getControlesTipoAPendientes() > 0) {
            avisosTipoA = true;
        }
        if (c.getIsTipoBVisible() && c.getComponenteTipoB().getControlesTipoBPendientes() > 0){
            avisosTipoB = true;
        }

        if (avisosTipoA || avisosTipoB) {
            // Añado la sección y los items.
            final SubMenu subMenu = menu.addSubMenu(c.getNombre());
            if (avisosTipoA) {
                subMenu.add("TipoA").setIcon(R.drawable.ic_tipoA);
            }
            if (avisosTipoB) {
                // subMenu.add("TipoB").setIcon(R.drawable.ic_tipoB);
                int itemId = subMenu.add("TipoB").getItemId();
                View menuItem = MenuItemCompat.setActionView(subMenu.findItem(itemId), R.layout.menu_notificaciones).getActionView();
                ((ImageView) menuItem.findViewById(R.id.ivMenuNotificaciones)).setBackground(getDrawable(R.drawable.ic_barcode));
                ((TextView) menuItem.findViewById(R.id.tvMenuNotificaciones)).setText("TipoB");
                ((TextView) menuItem.findViewById(R.id.tvContadorNotificaciones)).setText("100");
            }
        }
    }
}

And the "menu_notifications.xml" file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:orientation="horizontal">
    <ImageView
        android:id="@+id/ivMenuNotificaciones"
        android:layout_width="64dp"
        android:layout_height="match_parent" />
    <TextView
        android:id="@+id/tvMenuNotificaciones"
        android:layout_width="wrap_content"
        android:layout_height="match_parent" />
    <TextView
        android:id="@+id/tvContadorNotificaciones"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="right"/>
</LinearLayout>

However the menu does not load the "menu_notifications" view.
