--- **Global Course Rating: 4.20** ### Course Overview The course has received overwhelmingly positive reviews from recent learners. It is appreciated for its digestible length, clear progression from basic to advanced expressions, and effective summary sections that aid in revision. The course is highly recommended for beginners and even intermediate users looking for a refresher on regex. **Pros:** - **Digestible Content:** The course is not overly long or complex, making it accessible for beginners. - **Clear Progression:** The material progresses from basic to advanced expressions, which is beneficial for understanding the concepts. - **Educational Structure:** The inclusion of summaries at the end of certain sections helps learners revise and reinforce their learning. - **Audio Clarity:** Despite some keyboard noise, the audio quality is clear and the instructor's teaching skills are commendable. - **Real-World Applicability:** The course provides a great introduction to regex in Python, with practical examples that can be applied to real-world problems. - **Comprehensive Coverage of Basics:** For those starting from scratch, the basics of regex are covered well. - **Positive Impact:** Many learners report a change in their perception of regex, viewing it as less intimidating and more useful after completing the course. - **Free Course Benefits:** As a free course, it covers many fundamentals and practical examples, offering good value for the cost (none). **Cons:** - **Advanced Topics Absent:** The course does not cover advanced regex topics such as lookaheads, lookbehinds, atomic groups, and non-capturing groups. - **Exercise Complexity:** Some learners found the examples too simple, and there is a call for more difficult exercises to test the learned skills. - **Incomplete Content:** At least one learner pointed out that backreferences and other topics should be included. - **Quiz Issues:** There are corrected options in quiz questions, indicating some inconsistencies within the course materials. - **Pytest Coverage:** The section on Pytest is considered too basic and not as detailed as the Selenium content, which may not fully prepare users for interviews or advanced use cases. - **Keyboard Noise Distraction:** Although it's a minor issue, some keyboard noise can be heard in the audio recordings. - **Lack of Advanced Concepts:** The course is more introductory and does not delve into complex use cases, which could limit its usefulness for advanced learners. ### Learner Experience Learners have had a mostly positive experience with the course, with many praising its clarity and practical approach to teaching regex. However, some have highlighted areas for improvement, such as incorporating more advanced topics and providing challenging exercises. **Recommendations for Further Learning:** - **Advanced Courses:** For those looking to delve deeper into regex, it is recommended to follow up with more advanced courses like Chandra Lingam's course on regular expressions in Python, which covers more complex use cases and offers challenging exercises. - **Continued Practice:** Learners should seek out additional resources or challenges to test their skills after completing this course. - **Real-World Application:** Apply the knowledge gained from the course to real-world data cleaning and automation tasks, such as using regex with Selenium or Pytest. ### Summary This course is a solid introduction to regular expressions in Python, particularly for beginners. It covers the basics well, provides clear examples, and has a structured approach that facilitates learning. While it lacks some advanced topics and detailed coverage of certain libraries like Pytest, it remains a valuable starting point for those new to regex or programming in Python. Learners are encouraged to seek additional resources for more complex regex patterns and exercises to further enhance their skills. The course's positive reception, coupled with the suggestions for improvement, indicates a strong foundation that can be built upon for more advanced learning.
