It was quite enjoyable to be taught with paper and pen instead of a screen.

[@valleconexoes]

Exactly!

[@NG__________]

I'm just add a comment on a paper post-it to say "you're right!"

[@sivaboyidi9939]

Exactly. It’s been a loooooooong time we saw a paper and a pen 😁

[@Shubham-bt5iq]

true

[@sukruthas1646]

Yea it's kinda cute

[@pankaj3746]

I have 10 years IT experience and so far I never bother learning about regex, yet the irony is i almost use it on day to day basis. I simply Google and copy-paste the regex. Your video helped me understand the basic concept very well!

[@vistarshikhare8555]

Where are u working ?

[@stanknight9159]

This is the same lol. I am a developer and IT guy. RegEx gives me headaches more than anything else. Overall, it is simple but my memory refuses to accept it lol.

[@PraveenKumar-uj2ih]

Same thing I always done...

[@PoRoKLusT]

true, there are a lot of templates for regex. Sometimes happen you need to write your own in a specific situation like validation but it's simple case.

[@ndk8111]

Tsk-tsk.

[@JeanBMbaya]

Wow, with a calm voice and temperament, you’ve made it so easy to understand and apply by providing many typical examples....thank you!

[@sagarjha9021]

I've been struggling with this Regex for many hours , but now its all clear just in 10 minutes .. Thank you

[@dariuszfilipek3519]

In the second task You have a little bug. The task "only one digit allowed in between" indicates that the last [a-z] should have not * (0 or more) but + (1ore more). Otherwise the digit will not be between the letters. Everything else is just beautifull and simply shown

[@vigneshm7930]

Yes

[@xantaclaws]

Yes

[@synaxreader9326]

That is what was thinking. Liberating to become the master after 10 minutes of a tutorial.

[@KK-wk1id]

They should pin this comment

[@prabhatsingh6124]

* is for the number of repetitions not for the number of characters for instance [a-z] * simply means it should atleast have 1 character between a to z and * there means 0 and more repetitions are possible do correct me if I'm wrong

[@cecomecoev4796]

Greetings from Bulgaria. So good tutorials and so nice voice. I wish I could give you one thousand likes.

[@JoolieJulie_]

i can't believe i binged watched 5 videos without really understanding more than before, until i had to fall on this video finally thanks so much, i feel less anxious about my classes lol

[@Sapphiamur]

Still the best regex tutorial I've encountered so far. Thank you so much! 💜

[@Frogstomp_actual]

Well done, i am now getting my staff to do this old school pen and paper to reinforce learning.

[@varung9429]

Thank you so much for this. Simple and clean. What was otherwise a scary topic for a non-geek like me, you have made it sound like its nothing :)

[@komaljaswani7497]

Same for me! When I google searched REGEXP POSTGRESQL, I could hardly understand anything :( This video made it way simpler! :) Thanks a lot! :)

[@sureshjace]

Thank you good explanation.. in 2nd example only one digit allowed in between so we can add {1} after (0-9)

[@Phomec1an_]

Regex has always been complicated to me but thanks to this video,I am capable to understand the basic concept! Has been searching this type of video for a long time also I HAD MISSED THIS PEN-PAPER THING! I love it when someone tries to explain with pen & paper

[@HumorHubIndi]

at 10:19 ," com " needs regex : [ a - z ] { 2 , 4 } ,as it allowed at least 2 characters and less than 4 characters (as you explained { y , z } earlier ).

[@rhutikchaudhari769]

here, after dot([\.]) there is only contain ".in" or ".com" :)

[@harshitanand8216]

Is [e-mail] valid email according to that regex...?

[@Pramod-wq7ef]

yeah, wanted to ask the same @Abhinav Garg

[@raakeshahuja]

@@harshitanand8216 yes if u want underscore not to be at first place then use it separately after characters

[@JF098]

I've looked everywhere for a good, simple explanation of how to start writing REGEX expressions and I finally landed on this video. THANK YOU!!! Also had a few good laughs during the lesson. "I'm sorry it doesn't look like capital W" LOL

[@shahnawaz20011]

i was finding some solution for my project but got it through ur concept, thanks for help.

[@zeeshanahmed2594]

Thank you very much Madam for this clear explanation. The third example was all inclusive. It would have been better if you had included one table with an SQL query.

[@andrewburnley917]

Excellent, this was one of the best tutorials I have watched for some time

[@RajuMandala1]

Kudos from an app sec engineer who is banging his head understanding ReDoS attack. Now it is clear.

Hey Hi Thanks for this great video, I wasted my time from morning to understand this regex but u explained propely. I can see my comment on this video 2 years back when I was in college on that time this video helped me and now also this helped me. Thank you🙏

[@noreply_youtube]

nicely prepared, narrated, content understandable

[@luukh5229]

Many different websites tries to teach me quickly, this video is my reference now.

[@vikkimcewen]

This is one of the best regex tutorials I've ever seen. My stupid brain lacks few braincells but this one is really an exception. Kudos

[@dhairyataneja3211]

Amazed by your calm way of teaching

[@vaibhavpatil6395]

It's really interesting and informative. I am working as a python developer but still not have much knowledge about that regex pattern criterias. You explained it much easily

[@avinashkumargond3291]

Its really a nice video All the confusion about regex have now cleared.. thank you

[@harikrishnanb1752]

Brought back memories, nice to see this video

[@ayushp8790]

It was better than the 2 hour lecture that i attended yesterday, thanks 🤠

[@AdamantMindset]

damn easily the best one. once you understand the concept you can implement in any coding language. i was watching specific java tutorials for this and couldn't understand anything

[@ramanr9935]

Thank you for your clear presentation on paper and taught us patiently ❤

[@ritikaverma6498]

Thanks a lot. U inspire to be very polite ☺️ @6:43 should it not be + instead of * because the rule says it DOES Contain lower case, so it should happen one time or more times(the rule for +)? I felt it should be both pluses? Because there has to be a lower and an uppercase (can't be zero, so no *) and there has to be a number in between. So both pluses?

[@SumonAhmed-bo1te]

I thought the same

[@bezawadaharikrishna4889]

Indeed

[@zxxczczczcz]

so 2 pluses or...

[@technicalmove2764]

Very nice explanation. I understood the whole concept of regex in one go. Brfore watching this I thought how i will wrote my custom regx.

[@kevalrane1761]

ohhhoooo thanku... apaka ye upaker hamesha yad rahega muze

[@Dmittry]

I actually love it is handwritten.

[@tharushadilshan7054]

Excellent content. Perfectly understood it. Thank you so much.

[@engineerplanet5704]

Thanks for this video.first time learned regex with this much simplicity

[@AjayAbhishek240]

You have really taught everything in a very very brilliant way....... and I understood a lot crystal clear...... lots of thanks from me........

[@wick_bourne]

Thanks! : ) My view: Not everytime, everything need to be explain using computer .You did great.It cleared my basics. After your video I watched video on redex by codebasics which is helpful for practise.

[@jsmphompho8052]

I am new to programming. Thank you for your work. 1. I'd like to know, on your answer for question 2 you used * instead of + which according to me is what will make sure that there is atleast one lowercase 2. on the last question you chose to use {2,3}, if I understood your explanations well that quantifier will allow only 2 chars since 3 in not included. {y,z} means atleast y times but less than z times. So according to my small understanding {2,4} would be more accurate in this case. please do correct me if I am wrong. by the way this content is the best

[@neinheart7801]

the best regular expression video so far

[@nkgajjar]

Explain superbly example was great and your voice is extraordinary. To learn with you is very enjoyable.

[@parthparth8680]

Very Nice EXplaination but [ ]{Y,Z} ==> OCCURS ATLEAST Y TIMES --> OK BUT LESS THAN Z TIMES SHOULD BE BUT NOT MOTE THAN Z TIMES

[@amarjeetverma6965]

Thank you so much I just started working in regex after watching this video.

[@Lonewolfcoder]

Well Explained thank you alot. I am your fan and subscriber now. You teach very well.

[@deepanshusingh9943]

In example 2, i think it should be " [A-Z][a-z]*[0-9][a-z]+ " as it is written that the digits should be in between of these

[@ChandanKumar-ni7ll]
