Python YouTube API Tutorial: Calculating the Duration of a Playlist

[@coreyms]

Hope everyone is having a great week so far. In this video we're going to be writing a script that I've personally used a lot to calculate the total duration of KZbin playlists. If you have any more suggestions of what you'd like to see us use the KZbin API for then definitely let me know. I have a few more videos in mind of what I use this for personally, but I'm also interested in hearing your use cases as well. Thanks!

@Corey Schafer: do you really watch youtube courses ???

[@coreyms]

@@zaabimahdi Oh yeah, all the time. Not always programming. Sometimes it can be a college course or some other field of study I'm interested in.

[@SalimHamood1]

@@coreyms can you make ml script that predicts corona cases ?

[@zaabimahdi]

@@coreyms very interesting and motivating to read this comment from you... Thank you !

[@i_v_t]

Can we download the playlist using this?

[@HamroMotors]

Best Teacher for me all over Internet This guy is giving all his videos for free ... really appreciate man

[@ForTheGreaterGood]

You can say that again

[@jimshapedcoding]

Corey Schafer OOP and also Django literally took my Programming level from beginner to great level, a level that gave me enough confidence to give my own shot with Python series Thanks for teaching us a lot Corey, You are still number 1 in all Python communities that I'm a part of. ;)

[@sekekeretsu4172]

My fav python and programming language course channel on youtube. The video length are right for my attention span. Also the accent is a plus. Definitely recommending it to my colleagues.

[@theanswer3sixers]

If anyone else wants to avoid regular expressions, they could do the following. KZbin duration is in ISO 8601 format, so I used the *isodate* library (pip install isodate) and used its 'parse_duration' method which returns a timedelta. So the code at that point simply becomes: for video in video_response['items']: iso_8601_duration = video['contentDetails']['duration'] dt = isodate.parse_duration(iso_8601_duration) total_seconds += dt.total_seconds()

[@coreyms]

Nice! Definitely a better solution than I used.

A much-needed video. I've been thinking to do this for a long time. Thank you so much for making it. I'll join the membership once I'll have a steady income to support myself. Thank you again for making such content free of cost and available to everyone.

[@dailydevtips]

Well articulated tutorial. I used this tutorial to calculate the the total length of all videos on Corey's channel. This is what I found. 77:16:47

The best instructor in every subject

[@bohdan134]

Recently i just search service for make this calculation.. and now you made guide about it! Awesome! Thanks! Like!

[@Special_Sharpie]

Corey, you are an absolute legend, I came across your tutorial videos a while back and was blown away by how in-depth and non specific they are. Whenever I am looking into a new module or python feature, I check to see if I can find one from you! Keep it up! With your help I have almost mastered API scrapping, working with JSON files and much more! THANK YOU!

[@justin3594]

I’m so happy to see these api videos. To me they are the most useful thing ever. I would love you to cover how to setup an app to maintain local data from an api or scraping. In other words we can pull the data down, but how do I put it in a database and get it to update ever day or so? That would be gold.

[@obi666]

You' re doing great job making these tutorials. I really respect people who make quality and usefull stuff for free. Keep it up!

[@tony99659]

Corey, you are the most amazing teacher youtube will ever have!

[@netafeliciano6126]

You and Ahmad Bazzi are my go-to python channels !

60 hours on social medias?: NO 60 hours watching Schafer's videos: YYYYYEEEEES

[@veryexciteddog963]

Corey makes watching over half an hour of video to learn how to see a value that KZbin could have just included in the API if they weren't braindead much more bearable.

[@tejasvix]

Liking and commenting before watching the video is must for this Channel....

[@DanielLavedoniodeLima_DLL]

Awesome video as always, Corey. I already programmed a lot in Python throughout college, but your videos made me understand way better a lot of concepts I thought I fully understand, only to realise I missed some details that made a difference later. You're a great teacher, thanks a lot! May I suggest 2 topics I find it hard to find content about: - Django REST framework - Create an executable and GUI for inputs in a Python script (this one would make a big difference to me, as it allows people that are not familiar with programming to use my scripts) Again, thanks for the quality content and I hope I can contribute to you after I graduate from college. For now, I recommend your videos to everyone that asks me for help learning Python

[@thekitten117]

I like to watch at 1.75 speed. A small adjustment is required. Great vid!

[@gambomaster]

You are one of my favorite teacher. Thanks man. 👍👍👍

[@ThomasGabrielsen]

This was a great tutorial to getting started with KZbin API. I'll check out more of your videos. Your Python tutorial playlist is currently impressive 62:9:43 long. Thank you! :-)

[@radonspace2098]

To be precise: 62 hours: 9 minutes: 42 seconds. 😉

[@ThomasGabrielsen]

@@radonspace2098 D'oh! :-)

[@ramshankarkumar4222]

Hey ..... I just made this youtube playlist time calculator using Selenium and Beautifulsoup . Using selenium and Soup it was little bit tricky but for understanding the web scrapping part it was very essential for me to go with those. And thank you so much sir for uploading this video usin KZbin API because for sure it will be much faster than my selenium and soup script and it removes many corner cases that i was facing in my script.... Again a big thnks for this :)

[@saralgyaan]

your videos are best. I learn a lot from you on daily basis. Thanks a lot....

Very useful - thank you. I've added user playlist input so there's no need to change id manually each time.

[@antonie9034]

Thanks Corey I've learnt alot from you than in any classroom ever. Ive been learning Data science and I think I havent learnt about Numpy [Numerical Python] Kindly do a video on that

[@processorbot8761]

Thank you so much Corey! Just what i needed to help me execute a project idea!!

[@DSD]

That was great! I'm coming to this from the wrong video so my credential part is grabbed differently and I could get the code to run correctly from the download - but I followed along and got it to work. My playlist has 376 hours 22 minutes and 59 seconds. Would like to try to use this to go through the subscriber list and the member list but can't get that to work right. WIll have to try again after getting this to work.

[@letampatrickbienwi4610]

Great video Cory, I feel really empowered to tackle in depth python projects. Wouldn’t it be simpler having a function that treats the duration as a string and extracts each value based on when the current value in the iteration is not a digit? Thank you once again!

[@rangavembar]

Awesome!!

[@an4s911]

Hey there 👋😂 Corey Scafer, I love your content and your python tutorials are just so amazing and really explained. Even though I've learned python from a lot of different sources and have found many really good ones, I always come back to your channel to check if you have anything about it because I understand more better in your videos. And also I started learning python in the beginning was from you. Im just a beginner programmer, and what I want to recommend/suggest is that I wanted some tkinter tutorial, and in most of the other KZbin channels I don't find content that is as good as yours. If you'd like please upload a tkinter or just some GUI Python tutorials. Thank You very Much 😄

Hi Coery, great video, thank you for all your tutorials, it helped me incredibly to boost my career.. Do you think it would be possible to do video about new dataclass that came up in python3.7? I am thinking about using it for my automation test data, but I not sure about all of it ups and downs and since I am still a newbie, a video from you on this topic would help me a lot. Thank you and keep up the awesome work!

[@tanmaydeshpande]

I'm pretty sure that you could just use pytube to get the duration of all the videos within the playlist and then simply add them up to get the actual duration of the playlist.( I believe there are finer options within the method to get specific format of duration)

[@mukeshrar265]

The Zen of Python, by Tim Peters Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. Readability counts. Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you're Dutch. Now is better than never. Although never is often better than *right* now. If the implementation is hard to explain, it's a bad idea. If the implementation is easy to explain, it may be a good idea. Namespaces are one honking great idea -- let's do more of those!

[@sebastiancaro7713]

Hey Corey! Quick question: I followed this tutorial all the way through and when I printed out the hours, minutes, and seconds. I got the wrong time. It gave me 62:9:44, do you know what the issue might be? (My code is exactly the same as yours) PS: Love your videos man, excellent educational and very entertaining tutorials

[@marklonganbach3268]

Hi Sebastian, I also received the same timestamp as you. Corey's original video was posted several months ago, and if you watch closely you'll see he had 140 videos in his playlist. As of my post's date, he now has 143 videos. I'm guessing the 3 additional videos add up to the extra ~90 minutes seen.

[@Veptis]

Need to do that for my watch later and also check the average hours per day

[@daito9163]

Before 2 minutes of this video,i just calculated his *Python Tutorial* playlist duration manually and it took 10 minutes to calculate 143 video's duration 😅.

Hello Sir, thank you for sharing with us. How can i get, the time a person actually watches a video? ( ex: if a total duration video is 10 minutes but I have watched only 4 minutes).

[@rauhan_sheikh]

Is this outdated now? coz I can't find the username or userid of the channels from URLs, it seems that those URLs do not contain username anymore?

[@AlexMelemenidis]

Hi! It seems KZbin has switched to a different concept Handle, and the respective function parameter "forHandle". I was not able to find my username anywhere in the youtube settings... @coreyms: maybe add this to the video description? Or if possible even add it as image overlay (or subtitles) in the video?

[@fowad27]

How would I need to modify the code to find the duration of my watch later playlist? What I gather from the documentation, the watch later playlist cant be queried in the same way as the other playlists. Great video btw

Would multiprocessing or threading be appropriate for speeding up this script when calculating the duration for each video in a playlist?

Thanks Corey. Is there a quick modification that could use this script to calculate total duration of all videos on a channel?

[@Just2Dimes]

I tried this and it wasn't trivial in my experience, but I found this that made it a lot easier: github.com/youtube/api-samples/blob/master/python/my_uploads.py It's python 2 code though, so alter the 'print' statements, but this should work to get a list of all video_ids for a channel and then you can use Corey's code
