## org.python.core
Class PySequence

    java.lang.Object
      org.python.core.PyObject
          org.python.core.PySequence

All Implemented Interfaces:
  Serializable

Direct Known Subclasses:
  AstList, PyArray, PyBaseString, PySequenceList, PyXRange

    public abstract class PySequence

extends PyObject

The abstract superclass of PyObjects that implements a Sequence. Minimize the work in creating such objects. Method names are designed to make it possible for subclasses of PySequence to implement java.util.List. Subclasses must also implement get, getslice, and repeat methods. Subclasses that are mutable should also implement: set, setslice, del, and delRange.

Method Detail

### __nonzero__

    public boolean __nonzero__()

  Description copied from class: `PyObject`
  Equivalent to the standard Python __nonzero__ method. Returns whether of not a given `PyObject` is considered true.

  Overrides:
    `__nonzero__` in class `PyObject`

### __iter__

    public PyObject __iter__()

  Description copied from class: `PyObject`
  Return an iterator that is used to iterate the element of this sequence. From version 2.2, this method is the primary protocol for looping over sequences.

  If a PyObject subclass should support iteration based in the __finditem__() method, it must supply an implementation of __iter__() like this:

       public PyObject __iter__() {
           return new PySequenceIter(this);
       }

  When iterating over a python sequence from java code, it should be done with code like this:

       for (PyObject item : seq.asIterable()) {
           // Do somting with item
       }

  Overrides:
    `__iter__` in class `PyObject`

### __eq__

    public PyObject __eq__(PyObject o)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __eq__ method.

  Overrides:
    `__eq__` in class `PyObject`
  Parameters:
    `o` - the object to compare this with.
  Returns:
    the result of the comparison.

### __ne__

    public PyObject __ne__(PyObject o)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __ne__ method.

  Overrides:
    `__ne__` in class `PyObject`
  Parameters:
    `o` - the object to compare this with.
  Returns:
    the result of the comparison.

### __lt__

    public PyObject __lt__(PyObject o)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __lt__ method.

  Overrides:
    `__lt__` in class `PyObject`
  Parameters:
    `o` - the object to compare this with.
  Returns:
    the result of the comparison.

### __le__

    public PyObject __le__(PyObject o)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __le__ method.

  Overrides:
    `__le__` in class `PyObject`
  Parameters:
    `o` - the object to compare this with.
  Returns:
    the result of the comparison.

### __gt__

    public PyObject __gt__(PyObject o)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __gt__ method.

  Overrides:
    `__gt__` in class `PyObject`
  Parameters:
    `o` - the object to compare this with.
  Returns:
    the result of the comparison.

### __ge__

    public PyObject __ge__(PyObject o)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __ge__ method.

  Overrides:
    `__ge__` in class `PyObject`
  Parameters:
    `o` - the object to compare this with.
  Returns:
    the result of the comparison.

### __finditem__

    public PyObject __finditem__(int index)

  Description copied from class: `PyObject`
  A variant of the __finditem__ method which accepts a primitive `int` as the key. By default, this method will call `__finditem__(PyObject key)` with the appropriate args. The only reason to override this method is for performance.

  Overrides:
    `__finditem__` in class `PyObject`
  Parameters:
    `index` - the key to lookup in this sequence.
  Returns:
    the value corresponding to key or null if key is not found.
  See Also:
    `PyObject.__finditem__(PyObject)`

### __finditem__

    public PyObject __finditem__(PyObject index)

  Description copied from class: `PyObject`
  Very similar to the standard Python __getitem__ method. Instead of throwing a KeyError if the item isn't found, this just returns null. Classes that wish to implement __getitem__ should override this method instead (with the appropriate semantics.

  Overrides:
    `__finditem__` in class `PyObject`
  Parameters:
    `index` - the key to lookup in this container
  Returns:
    the value corresponding to key or null if key is not found

### __getitem__

    public PyObject __getitem__(PyObject index)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __getitem__ method. This method should not be overridden. Override the `__finditem__` method instead.

  Overrides:
    `__getitem__` in class `PyObject`
  Parameters:
    `index` - the key to lookup in this container.
  Returns:
    the value corresponding to that key.
  See Also:
    `PyObject.__finditem__(PyObject)`

### isMappingType

  Overrides:
    `__setitem__` in class `PyObject`
  Parameters:
    `index` - the key whose value will be set
