Is Dr. Angela Yu’s 100 Days of Python a good starting point for cybersecurity?

A free university-style Python course may be a stronger option if you want a thorough foundation. The University of Helsinki’s Python Programming MOOC is commonly recommended because it has lots of exercises and gradually covers more advanced programming concepts. After that, move into Linux, networking, and security labs.

Dr. Yu’s course is well structured and beginner-friendly, but it can feel slow if you already know the basics. For cybersecurity, focus on Python topics like file handling, sockets, HTTP requests, automation, regular expressions, and working with the command line. Build small networking and scripting projects alongside the lessons.

Don’t rely only on video courses. Use whatever course you choose, then practice by writing tools such as a log parser, port checker for your own systems, HTTP client, file-encryption experiment, or simple automation scripts. Hands-on security labs are also useful once you understand the basics.

Some people find commercial beginner courses become less consistent later on. University courses and well-reviewed programming curricula are usually more rigorous, so compare the syllabus and exercises instead of choosing based only on the instructor’s popularity.
