Python Pandas Tutorial (Part 4): Filtering - Using Conditionals to Filter Rows and Columns

[@Skandagupta-theHunSlayer]

There's nothing in your videos that can't be understand. Absolutely crystal clear explanation. Thanks Corey, 4 years later, from India.

[@qualjyn2]

Nothing like waking up a Saturday morning, and catching up on Coreys Python Pandas tutorial over a good cup of coffee :) @Corey, keep up the good work - it is really appreciated!

[@sidneysousa3520]

I said it! This is like Netflix :)

[@onyekachinelson6999]

Okay. Today is Saturday. Lemme watch it and see for myself. Thanks!

[@onyekachinelson6999]

The lesson is fantastic 👏

[@darshantawte7435]

Even in 2024 this is still the best tutorial out there for pandas. With AI becoming capable of performing EDA and data analysis (atleast elementary which is still better than many newbie analysts), i wonder how pandas will keep up with it.

[@douma8037]

bro but i guess building large scale AI models from scratch will definitely need pandas regardless of AI being able to do EDA and Data Analysis

[@darshantawte7435]

@@douma8037 Yeah data cleaning will play a major role even in the future.

[@douma8037]

@@darshantawte7435 yes! We’d need pandas for that.. unless some AI comes into play of course..

[@cordularaecke]

This is the best explanation of pandas dataframe boolean filtering I've ever seen - especially the inverse filter using the tilde - excellent - this is SO useful. Thank you

[@parols1160]

I guess 'flawless' is the only appropriate adjective for this whole series you are doing. Congrats from Italy Corey, keep it real!

[@ashylarry3442]

I let your ads play all the way thru. Fives minutes in exchange for what you’re giving...light work. Keep it up brotha!

[@tolulopeadedoyinadedoyin5239]

Corey is the best tutor , I have seen so far....He explains with ease and simplicity....More grace

[@mintymintfresh]

There is no better teacher on python than corey... He is simply the best one... I got to learn flask .. All thanks to corey.. There are thousands of students whom u are making a better programmer every day ...

[@Shaillha]

I have referred to three video tutorials/courses before this and this is by far the best course on pandas with complete coverage. You deserve a million likes for this series. This course is priceless.

[@akiratoriyama1320]

Like THE BEST pandas tutorial on internet. Thanks again Corey!!

[@motlatsimoea]

Of all the teachers I have come across on KZbin, you are my favorite. The way you explain. The example exercises you use are simple enough to comprehend while also making me feel like I could handle bigger problems. I learned Django from you as well. Thank you for all your work!

[@j3553hh]

Your videos are so rich with practical guidance that I'm pausing every 90 seconds to make notes. This one took me three hours to get through.

[@larz4437]

The often imitated, never duplicated, Corey Schafer. You're truly the python guide GOAT and us noobs bow before you. Thank you so much for this series and all your work.

[@niralpatel3369]

You're a great man Corey Schafer, This is the best channel ever on KZbin. Thanks form India.

[@edilgin]

i started learning python basics with you and i just cant believe how much i improved myself this year, thanks a lot!

[@shanplays6001]

Great series. I would recommend going through these tutorials once with the given dataset, and then going through it again using a dataset you're interested in. Dw, it will go alot faster the 2nd time around, and you'll get great practice actually finding insights you care about.

[@fuzzywuzzy318]

I'am from china !!!!!I am your new audiance ,and feel your video is really helpful!!!!!!!thanks!!!

[@cudanakiju0]

I'm reviewing your tutorial for my interview, that's awesome! Just to clarify one thing (part staring at ~7:00) - when combining conditions, you MUST put separate conditions into parenthesis, otherwise pandas will most likely throw quite ugly and non-intuitive error. I think that should be stressed, wasted some time on it once ;)

[@Historiaplaying]

Corey, you're a god of teaching, you don't leave out anything unexplained. Thank you

[@JoshBauerMuranga]

Your contents will never go obsolate mate. Pure Gold.

[@pierreroux-lafargue8227]

You're a good man Corey Schafer, thanks for the quality content.

[@MeherabHossainRaiyan]

I think it is the best tutorial i have ever seen in youtube. Good explanation sir.

[@JoshuaDHarvey]

19:22 let us know when you do a video on strings! Can't wait for that and if you need any suggestions on any of the methods in the pandas .../text.html let us know! Thanks for all your hard work Corey!

[@pythonstuff8633]

Bro you have no idea what help you are giving us.Thank You Keep doing what you do!

[@in_ashish]

Corey is the reason i will be able to earn my bread and butter. Can't thank enough!

[@sergiomunozblanco3843]

I don't understand the people that vote negative to these video lectures. They are really clear, they are concise, they are practical and they are interesting. Why?

[@kapibara2440]

These must be some internet troll, no need to thank about them. Just ignore them.

[@akintonaolawalesamuel2236]

Lucid. Concise. Thanks a bunch, Corey, for all you do to make us Pythonistas

[@TopBagon]

Your tutorials are the best ones I've ever seen in my life ._. thanks you so much for those, we appreciate this a lot *Simply Amazing*

[@nascentnaga]

this is fresh in 2024 :)

[@Lars7878]

I love that .Str.contains filter, that is a brilliant idea, I never came up with.

[@chrissteele9540]

You have a way of making any topic seem sooo simple... You're an incredible teacher! I owe most of my python skills to you btw ─ thanks :) Please keep the videos coming!

[@clexyk]

Corey, your tutorials of Python are the best stuff I have ever seen. The ones on Pandas is again of very high quality.

[@josephsteen230]

As per your request: I would like to see you upload a video about truth tables. I like the way you explain things, Corey. Your Panda series is helping a lot. So thanks for what you do!

[@Rajesh-nb9de]

This is the best library to learn pandas... love from india

[@KeithFlint350]

4:20 if the filter is saved as a variable then you can easily use it many times in the code. Doesn't matter for a presentation at school, but matters a lot when you're building an actual app

[@robertobr234]

I have watched this video many times. When I forget how to use LOC I come here to remember. It's one of the most useful functions in Pandas.

[@Takk6]

I rarely comment but I've watched alot of Pandas tutorials on youtube and this is by far the best one Ive seen. Subscribed. Will you be doing a Scikit-learn tutorial in the future?

[@coreyms]

Thanks! And yes, I will be covering that, but I don’t have a timeframe of when this will be yet.

[@MrGokTR]

Thanks for sharing such an amazing series. You are basically representing the Zen of Python in person!

[@YeekyYeeky]

Corey Schafer is really great at explaining things , thank you very much !

[@kingveelatte41]

Found this channel couple weeks ago, and I watch it almost everyday know, like watching fiction series i love. Thank you Corey for amazing video (I forgot if I already comment like this in another video but yeah Thank you as always)

[@KeithFlint350]

Proper tutorial with a proper English

[@ndiayemodou3474]

There is also someone from Senegal west Africa :) you are amazing !

[@pouyarahimpour484]

When negated the filt statement (9:19) you should have said 'and' instead of 'or'. Thanks for this great series.

[@jasonbwaljones]

This is the holy grail series for Pandas in 2021

[@rishikambhampati2862]

Though we have an idea of the concept, there will always be something new to learn from your videos. As usual thanks a lot.

[@junaidmalik9593]

your playlist is amazing. to be honest i have taken dozens of courses online for python on many platforms but non of those have been completed beyond 20 %. looking forward to gain the skill here at least, as its fun to hear and v understandable

[@rudiklein]

What can I say...great job with this series. Again.

[@shamseshifat7825]

Your in-depth knowledge in python is astonishing! The thing that always amazes me is, when you finish explaining a topic and I ask myself " Now what if I try to do that?" kinda questions and within no seconds I see you explaining the same question! 😳 Do you mind read your viewers or what? 😅 Anyways, you are a legend

[@zahidkamil7833]

Can't wait for the string method you said in pandas. I am really looking forward for that. Thank you so much for all your effort and help! :)

Thank you again for these type videos, Please keep on posting these type of video in the future also.

[@thefireagen]

So far so good explanation..I have been watching the series since its started...I came again to revise. just a quick suggestion from my side...please give a suitable name to filter variable so that it will look readable if someone wants to understand whats happening.

[@crazybigworld9357]

Thank you Corey. You're one of my best Python Teachers.

[@dmitrishostakovich3156]

There's a little mistake at 9:20. The opposite of this conditional has & instead of |. So: filt_2 = (df['last'] == "Schafer") | (df["first"] == "John") ~filt_2 = (df['last'] == "Schafer") & (df["first"] == "John") Still, great videos. I'm very grateful. Please keep it up.

[@HaoranZhang-jc8fq]

Your lectures are so great!!

[@lilahinzelbergyifa292]

[@vijaybabu3923]

Very fluid explanation of Pandas 👌 thanks Corey !

[@dipanjan93]

@Corey Many thanks for posting your tutorials mate. These are super helpful getting started with Pandas. I have a doubt @6:03, you mentioned that you prefer to use df.loc[filt, 'email'] for filtering over a specific column, however I was able to achieve the same with df[filt].email as well ? Do you mind explaining this. Thanks. Cheers!

[@nicholasmaloof8378]

Would you be willing to do a video on numpy?

[@JoshuaDHarvey]

I'm pretty new to python in general but isn't most of pandas built on numpy, so I imagine there is quite a bit of common ground between the two libs?

[@alexandertsiolkovski5848]

@ 17:20, Corey, the doc for pandas 'contains' function says it has 'Regex = True' by default. I realized this when I searched for "C++" instead of "Python" when it gave me a "multiple repeat" error. In this case, it is essential to set regex to false or escape the '+' using "\".

I like your videos. I want to suggest another "pandas" topic: Making Pivot Tabeles. Yes its a Matplotlib thing, but when i change from excel to pandas and want to do "all the tipical stuff", i won't look for a Matplotlib Tutorial. So you can introduce that skill in the Pandas Series as well.
