What is the procedure to extract values from the object used in python?

Answer

To extract the value it requires the object type to be defined and according to the object type only the values will be fetched. The values will be extracted as:
• If the object is a tuple then PyTuple_Size() method is used that returns the length of the values and another method PyTuple_GetItem() returns the data item that is stored at a specific index.
• If the object is a list then PyListSize() is having the same function that is defined for the tuple and PyList_GetItem() that also return the data items at a specified index.
• Strings uses PyString_Size() to return the length of the value and PyString_AsString() that return the pointer to its value.
• To check the type of the object and the extracted values use of methods like PyString_Check(), PyTuple_Check(), PyList_Check(), etc are used.
