    Parameters:
    
    index - the key to lookup in this sequence.

public PyObject __finditem__(PyObject key)
```
    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:
    
    key - the key to lookup in this container
    
    Returns:

  - __delitem__
```
public void __delitem__(PyObject key)
```
    Description copied from class: PyObject
    
    Equivalent to the standard Python __delitem__ method.
    
    Overrides:
    
    __delitem__ in class PyObject
    
    Parameters:
    
    key - the key to be removed from the container
  - __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

```
public int traverse(Visitproc visit,
                    Object arg)
```
    Description copied from interface: Traverseproc
    
    Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter. If Visitproc.visit(PyObject, Object) returns nonzero, this return value must be returned immediately by traverse. Visitproc.visit(PyObject, Object) must not be called with a null PyObject-argument.
    
    Specified by:
    
    traverse in interface Traverseproc
  - refersDirectlyTo
```
public boolean refersDirectlyTo(PyObject ob)
```
    Description copied from interface: Traverseproc
    
    Optional operation. Should only be implemented if it is more efficient than calling Traverseproc.traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.
