Regular Expressions in Python | Regular Expressions Python Tutorial

Regular Expressions in Python. Regular Expressions Python Tutorial.
This video is a complete tutorial on Regular Expressions in Python. This is a full course on how to use Regular Expressions in python. Regular Expression is also referred to as REGEX. Using Regular Expression, we can search for a pattern of string in the given text.
Regular Expressions are a very powerful tool used to perform complex searches on a text. By specifying a pattern for the string, we need to search for, Regular Expressions can extract a string even if it is present in different format until and unless this string follows the same pattern as mentioned in the defined Regular Expressions pattern.
In this video, we go through the different steps to be followed to use Regular Expressions in python. We also explain the different character class, special characters and also all the Regular Expressions symbols or notations which can be used to define or create a pattern in Regular Expressions in python. We also write multiple python programs to create different patterns to match an email id, phone no and date values. Finally, we also cover the sub method in Regular Expression which can replace or substitute the matched string with a replacement string.
There are only 4 steps to be followed in order to use Regular Expressions in python:
1. Import re module which is the Regular Expressions module in python. All the functions and features required to perform regular expression search in python can be accessed by importing the re module.
2. Next steps is to create the Regular Expressions Pattern. Pattern is basically the format or structure of the string that we are trying to search. In Regular Expressions, we have several different character classes, symbols and special characters which will help us to identify every kind of characters or symbols hence making it possible to define a pattern to search of any type of string.
3. Once the pattern is defined, next step is to search for this pattern in the given text or data.
4. Finally, we extract all the matched string.

i do comment on you tube videos very rarely but this video made me so happy that i learned regular expression from biggner to advance .techTFQ has explained all the concept with numerical example and logic .it is the one of the best tutorial on regular expression on internet .Thank you sir may Allah bless you

[@magicmedia7950]

This video takes top position for regex tutorials on KZbin. I wonder why it is so underated

[@vadderamn2]

This tutorial is making Zero to Hero in regex concepts.... Awesome explanation with different examples.... THANK YOU SO MUCH techTFQ❤❤

[@clintwoodcb]

This is by far one of the best videos out there on Regular expression, very easy to follow...!!!

[@1982Dibya]

You are a genius man.The video cleared all my doubts in regular expression.Very well presented

[@user-ko9ti3lc4q]

Explainded very well..thankyou

[@jeevithaloknath9787]

very wonderful,super explanation.. Let me watch all of your videos.

[@senthilramana]

A minuscule mistake at 41:52, you are entering an escape character in the text. (Hi/?), I don't think that is necessary, as the regular expression should be done at compile and not in the text we are working on. But you have explained regular expressions so well that I could get clarity over the fundamentals Your teaching is really awesome!!! Kindly do a video, of when we should use re.match, re.findall and re.search & also how to export to excel. For example, in this video, if you have shown how to export to excel where it has 3 headings Dates, Email Id, Phone number and the extracted results should be populated under respective headings, it would helped us a lot. Thank you !

The most challenging is extractingvthe strings matching a give pattern. The we store them in a variety of ways and in diverse data structures. The extracted strings could be stored in temporary lists. Once we get the lists, we could easily create a pandas dataframe. That is one way to store the resulting matches in a tabular structured format.

[@sathyamoorthy2362]

Video is great i was working in oracle for sometime and need to know regex at that time i thought regex is different in each language but only later i realised most of the cases it is almost same,now i found this very late,I have to admit thoufiq bro you are one of the good teacher i found in last 6 months you are doing really a great work each one of your video is crisp and i never wasted a single minute.Once again thanks bro

[@sachinsuman8536]

Your way of teaching is very good. First you position yourself in the beginner's shoes and then you give solutions. You always think of how the beginner will try to approach a problem and you always say why one should or shouldnot approach the problem in a particular way. That's the best part. Please make video on hadoop with python for beginners. I think you can make us understand in simplistic way.

@@techTFQ I did the last pattern to get the phone numbers but still didn't get the last phone number? the pattern is "(\+\d)?\d{3}[-.]\d{3}\s?\d{4}", is there something I'm missing? Thank you!!

[@zubaydee]

@@techTFQ I did this pattern "(\+\d)?\d{3}[-.]\d{3}\s?[0-9,]+"" to get the last number as well.

[@siddharudtevaramani1055]

Hi, I am stuck with this question. unable to input the 'if' condition under RegEx. "write a function that highlights where two ‘o’ characters appear beside each other in the given string only if there is another occurrence of two ‘o’ characters appearing beside each other subsequently in the same line." can you please help

[@Hunter-di9by]

Hi sir. I have seen all your Videos.Your lessons are excellent especially SQL & Python. Now I'm currently studying data Engineering and start learning python.so I have a question which are the most important topics which should i cover.all this topics you are completely in your Lessons series. So this python are enough for a become a data Engineer.or some advace python I should learn.

[@techTFQ]

Thank you 🙏🏼 I have made a video on how to learn python, there I mentioned which concepts to learn in python, perhaps you can check that video

[@manuagarwal7738]

i enjoy a lot in your session .one thing i ask you that is it complete regex?

[@techTFQ]

Hi Manu, Thank you for liking the content 🙏🏼 There are a lot more you can do with regex but everything I covered in this video should be good enough to get started and perhaps more than enough to use regex in general.. But of course based on your project and requirements there may be other formulas to be used .. cannot cover 100% of regex in one video ..

[@jsmvlogs2001]

sir how can I take the input from user in multiple lines. please help me in this.!

[@prabukaliyamoorthy6970]

Hi Can you please include one pattern change(replace) to another pattern like date 02-02-2022 to 2022/02/02

[@prajwalks7254]

Tq bro

[@techTFQ]

Your welcome buddy

[@reigngamer94]

Sir Please make a video on Pandas,Numpy etc for Data Analysis

[@techTFQ]

Thank you so the suggestion Reign 🙏🏼 Actually I am currently working on making video about pandas, numpy and matplotlib .. hopefully in the next few weeks..

[@mdsaidulislamsayed6063]

is it possible to make a video on RegEx for Bigquery?

[@techTFQ]

I’ll consider it bro
