Our take

Based on the ratings of 821 students, a sample of their written reviews and the syllabus, as the course stood in June 2023. No course pays to be reviewed.

This is a short, language-neutral introduction to regular expressions from Jazeb Akram, a data scientist and freelance developer. It runs 5.4 hours across 61 lectures, and about 10,000 students have enrolled. The syllabus moves from characters to quantifiers, groups and assertions, then spends 19 lectures on projects: patterns for names, emails, URLs, IP addresses, dates, times, postal codes, card numbers and passwords. It is aimed squarely at beginners, and reviewers who came in as beginners call it a good fit.

Reviewers mostly praise the teaching. They call the explanations clear and easy to follow, and one says the project lectures cleared up confusion from the middle of the course. The complaints are consistent too. Two want exercises after each module, and one says the end exercises show the solution on the same sheet as the question. Another asked for the larger text files used on screen. Two mention an accent or delivery that is sometimes hard to follow. People who already knew some regex found it thin, and one notes that possessive quantifiers and atomic groups are missing.

The 4.7 rating from 821 reviews holds up. Of those, 693 are four or five stars, against 35 at one or two. The last update was June 2023, so the course is over three years old, though regex syntax changes slowly. There are no quizzes or coding exercises on the platform, so practice is up to the student. It works well as a gentle first pass. Anyone wanting depth should plan to move on to something harder afterward.

Best forComplete beginners who want a slow, example-led intro to regex plus ready-made patterns for emails, dates and passwords.

Skip it ifYou already know regex basics and want atomic groups, possessive quantifiers or harder exercises.

Pros

Reviewers call the explanations clear and easy to follow, even with no regex background
19 project lectures build patterns for emails, URLs, IP addresses, dates and passwords

Very good explanations and very easy to follow. Thank you very much Mr. Akram.

And this is the place where RE can make your work a lot easy,.

Knowing Regex, how to use regular expressions effectively is a valuable skill that can quickly take your skill-set to top. Logic in programming language requires a long coding work but regular expressions can do the same job within 2 to 3 lines.

RE act like a filter, and they will filter only relevant data which programmer asked for. So, They can save your time, reduce your coding work and increase your productivity. That's why, RE is a must skill for back-End developers and Data Scientists,
