| |
| The functions in this chapter are specific to certain Python object types. |
| Passing them an object of the wrong type is not a good idea; if you receive an |
| object from a Python program and you are not sure that it has the right type, |
| you must perform a type check first; for example, to check that an object is a |
| dictionary, use :cfunc:`PyDict_Check`. The chapter is structured like the |
| "family tree" of Python object types. |
| |
| .. warning:: |
| |
| While the functions described in this chapter carefully check the type of the |
| objects which are passed in, many of them do not check for *NULL* being passed |
| instead of a valid object. Allowing *NULL* to be passed in can cause memory |
| access violations and immediate termination of the interpreter. |

| Generic operations on sequence objects were discussed in the previous chapter; |

| intrinsic to the Python language. |
