This article will explain in detail how to create Python tuples by providing related functions in Python/C API. The content of the article is of high quality, so Xiaobian shares it with you as a reference. I hope you have a certain understanding of related knowledge after reading this article.

If you provide PyTuple_New() function in Python/C API, use it to create Python tuples. Then PyTuple_New() function is in the process of returning the tuple created.

Prototypes of Python/C API related functions

PyObject* PyTuple_New( Py_ssize_t len)

The parameters have the following meanings.

len: Length of tuple created.

After the tuple is created, you can add items to the tuple using the PyTuple_SetItem() function. The prototype function is shown below.

Python/C API Number Practical Steps in Operation Processing

int PyTuple_SetItem( PyObject *p, Py_ssize_t pos, PyObject *o)

The parameters are defined as follows.

p: tuple of operations performed.

pos: Position index of the item added.

o: Added item value.

You can use the PyTuple_GetItem() function in the Python/C API to get the value of an item in a tuple. The PyTuple_GetItem() function returns the value of the item. The prototype function is shown below.

PyObject* PyTuple_GetItem( PyObject *p, Py_ssize_t pos)

The parameters have the following meanings.

p: tuple to be operated on.

pos: positional index of item.

When a tuple is created, it can be resized using the_PyTuple_Resize() function. The prototype function is shown below.

int _PyTuple_Resize( PyObject **p, Py_ssize_t newsize)

The parameters have the following meanings.

p: Pointer to tuple to be operated on.

newsize: The size of the new group.

About how to create Python tuples by providing related functions in Python/C API, I hope the above content can be of some help to everyone and learn more knowledge. If you think the article is good, you can share it so that more people can see it.
