About this certification
The GIAC Python Coder (GPYC) certification validates a practitioner's ability to write and analyze working code using the Python programming language, with a solid understanding of core programming concepts. GPYC holders have demonstrated readiness to employ common Python libraries, create custom tools, collect information about a system or network, interact with websites and databases, and automate testing.
The exam covers Python language essentials, packet and data analysis, website and database interaction, regular expressions, exception handling and debugging, and AI-assisted Python workflows including LLM APIs, agent tools, structured outputs, and validation. GPYC is a Practitioner-level certification within GIAC's portfolio, reflecting hands-on cybersecurity skills validated through a proctored exam.
Who it’s for
The GIAC Python Coder certification is for information security professionals, Python developers, forensic analysts, network defenders, and penetration testers who need to demonstrate practical Python programming skills in a cybersecurity context. Candidates typically have some experience with Python or a similar programming language and are looking to validate their ability to automate tasks, analyze data, and build security tools.
Recommended experience
While GIAC does not mandate specific prerequisites, a working knowledge of Python or a similar programming language is strongly recommended. Practical experience with scripting, data analysis, or network operations will help candidates prepare for the exam. Familiarity with Python syntax, data types, and control structures; Experience with command-line tools and scripting; Basic understanding of networking concepts (TCP/IP, HTTP); Exposure to data analysis or log analysis

Short enough to finish, long enough to matter.
2Every answer explained
Not only which one is right — why the others are wrong.
3A discussion on each
Ask, answer, and vote. Every question has its own thread.
A question, and the idea behind it
Every question comes from a concept
These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.
The visual book
See it once. Carry it into the exam.
The pages shown here come from our AI-900 book — an example of how each concept is written in plain language and, where the idea needs one, drawn as a full page you can take in at a glance.

Why a picture, and not another paragraph
Three reasons, and each one is a real finding rather than a slogan.

Answer it with the picture beside you
This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.
It teaches · it does not count
A smartphone uses AI to unlock when the owner looks at the camera. Which AI capability is being used?
AImage classification
BFacial recognition
COptical character recognition
DObject detection
Look at the five steps. Detect finds a face, align straightens it, encode turns it into numbers, search compares it with a stored face, and decide answers one question: is this the same person? Classification would only say “a face”. Detection would only draw a box. Neither decides whose.
Then the page shuts, and it starts counting
The same questions come back with the book closed — that run is the one that counts. After it, your coach picks one thing for tonight, sized to the time you have, and brings pages back before you lose them.

We build from the official skills outline, not from a summary of it — 12 objectives, 116 concepts written under them, and free questions against every one. When GIAC (SANS) changes the outline, this page changes with it.
