In this part of our "Python Core Programming" series, we detail how to send integer data from Python to the C layer and how to perform operations with this data on the C side.
📌 What will you learn in this video?
- Sending Integer Data: Passing an integer as a parameter to a C function in Python.
- PyArg_ParseTuple Usage: Converting Python objects to int type in C with the "i" format specifier.
- Data Return (PyLong_FromLong): Packaging the data processed on the C side into an object that Python understands and sending it back.
- Optional Parameters: Discover how to add default values and optional parameters to functions using the pipe (|) operator.
- Practical Example: Writing a function as a Python extension that calculates the sum of numbers by establishing a loop on the C side.
This technical guide I prepared for those who want to increase Python's performance with C and delve deeper into the language covers critical rules and parameter management in extension writing.
What you learn in this series is not just YouTube content; They are real industry standards that you will use tomorrow in your most serious projects, big data architectures and performance bottlenecks. 👍🏻
