How To Use Functions In Python (Python Tutorial #3)

Tips:
1. Follow along as I explain to make sure you understand everything
2. Ideally, work with a friend so you can help each other when you’re stuck
3. If you want to learn faster than I talk, I’d recommend 1.25x or 1.5x speed :)
4. Check the outline in the comment section below if you want to skip around.
7. Have fun! If anything is unclear, please let me know in a comment.

Hello CS Dojo. I don't know if you are going to read this, but I just passed an Exam in Python because of you! Thank you so much! I spend like 10 hours to watch your awesome lectures :)

Learned more from you in an hour than 2 weeks of a course. Thanks for taking the time and effort. Much appreciated 🙏🏽

I started watching these tutorials yesterday and I figured out by myself how to use these functions to create a program to solve the quadratic formula. I know thats probably nothing for coders but I feel really accomplished and if anyone wants to see the code I can send it to you over email. I just feel really accomplished and I wanna share it with someone. This guy is such a good teacher.

5 years later and this video is still amazing! You just helped a total noob complete part of the cs50 course with this video. I had no idea how to do mapping with a function. Perfect explanation. Thank you

I know this is an old vid I'm commenting on, but you earned an instant sub (well, after 3 videos). Informative, understandable, well presented, quick. Great stuff for a beginner like me!

I absolutely love your videos. My father inspired me to learn programming, as in the past I’ve learned some but I’ve gathered a lot of laziness towards programming because of a lot of heavy school work. My father encourages me to just read the documentation and learn Python piece by piece, but I find that boring and hard to follow.
Your videos keep me going and they are professional and clear. Instead of buying courses on Udemy, I just use your courses and they’re amazing. Thank you so much.

Well, out of all of the different, gazillion sites and videos I have paid for and not paid for, you are, in the 61 yr olds opinion, The Best. Knowing what you are doing, and Teaching, are two different skill sets. In my business, just because you have intellect and mental ability, does not mean you will make money. You are doing quite well, starting with a base concept, then giving a practical example, then breaking it down to show how it works. Outstanding job, young man just outstanding. Also, Kudos on your English, bring multilingual myself, it can be a daunting task at times, but you have also done well here. Keep up the good work and I look forward to seeing your future success, by the way, maybe a paid forum might help keep a roof over your head? :)

I have been following along with Python Crash Course book in my spare time and anytime I get stuck on a problem or don’t quite understand what I’m doing I always come to your channel.
This video helped me understand functions a lot more.

Hey YK, I from Canada, Québec, Gatineau and I speak french more than english. I am an absolute beginners on python (leaning how to code). I want to let you know that all your Python tutorial are well explained and I love following your courses cause you take your time to explain step by step and I found this a great quality and skills you have. Keep continue what you do, teaching us, sharing your knowledge and more. Your great energy will bring you where ever you want and you will get what ever you need to accomplish your goals. 👍

I am 4 years late to this channel and 43 years late to Programming, but I am enjoying every minute of this series. Thanks YK and the entire CS Dojo team.

I thought the overview of functions was excellent. Covering what one can use functions for, quickly and concisely, ( be it mappings and returning calculations. ) as well as using of strings. Much appreciate. I've watched a few online Python vidoes and it's nowhere near as sysynced and easy to understand with useful examples as yours. Keep up the good work.

[alandempsey]

These videos are great. I like the way you organize and outline the tutorial at the beginning.

[youdonthaveto]

You are so helpful. I've grown up in a broke family and I don't have any money to buy course for learning Python. Your videos mean a lot to me. Thank you so much Dojo

[mashiburrahmankhan]

This is the best Python video so far. Your whole playlist is also extremely helpful. I tried to find other beginners python videos but yours is THE BEST, very well explained and elaborated! Great job!

I've been self studying using another website where I bought a course on sale, and I have been struggling so much with functions that I even stopped for 2-3 weeks because I just felt so dumb that I couldn't grasp what was being asked of me... this video broke it down so nicely that after so long I'm finally able to grasp what was being said all along. thank you for making this video, it has brought me back to coding!!
