```
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 something with item }

public PyObject pop()
```
    Removes and return the last element in the list.
  - pop
```
public PyObject pop(int n)
```
    Removes and return the n indexed element in the list.

                    java.lang.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
    
    Overrides:
    
    traverse in class PySequenceList
  - 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.
    
    Specified by:
    
    refersDirectlyTo in interface Traverseproc
    
    Overrides:
    
    refersDirectlyTo in class PySequenceList
