Python provides two general-purpose iterator objects. The first, a sequence iterator, works with an arbitrary sequence supporting the __getitem__() method. The second works with a callable object and a sentinel value, calling the callable for each item in the sequence, and ending the iteration when the sentinel value is returned.
Type object for iterator objects returned by PySeqIter_New() and the one-argument form of the iter() built-in function for built-in sequence types.

Return true if the type of op is PySeqIter_Type .

Return an iterator that works with a general sequence object, seq . The iteration ends when the sequence raises IndexError for the subscripting operation.

Return true if the type of op is PyCallIter_Type .
2.2 版新增。
Return a new iterator. The first parameter, callable , can be any Python callable object that can be called with no parameters; each call to it should return the next item in the iteration. When callable returns a value equal to sentinel , the iteration will be terminated.
