Hi YK , In india we are not taught what we want . There is useless matter in our syllabus. Even many people with master degree in computer science can't create any simple application without any GUI interface help and swing controls. They teach us for marks not for knowledge. Should I learn computer science online leaving my school ?

My Professor thinks he's the real shit in Python by creating videos that are 5 hours long just to explain one concept!!!! Now, this is called a real teaching video!!!! short and informative!!!

[@elkresurgence]

maybe your prof really delved into that concept during those five hours. Short isn't always good, although in the case of this tutorial it is

[@joeroganpodfantasy42]

Maybe if your professor would release his videos on youtube people would appreciate them more. I have noticed people tend to dislike what it's offered to them locally or thru a system and they like what they find themselves online.

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? :) The Ever Kudoing VIPER

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.

Instead of buying courses on Udemy, I just use your courses and they’re amazing. Thank you so much.

Your tutorial is amazing clear and detailed, really amazing work.

[@xodiaki]

my solution: miles = int(input("Enter the amount of miles you'd like to convert :")) def convert(miles): return miles * 1.6 km=convert(miles) print(km) kms=int(input("enter the amount of kms you'd like to convert :")) def convet_km(kms): return kms/1.6 mile=convet_km(kms) print(mile)

[@rinovichaz3168]

If you convert your input as float instead of int it will be more accurate i think. I tried ur code using the input of 100.99999 an the conversion was a little off... using a float instead of an integer will not ignore decimals and therefore will give you the most accurate result. But ur code helped me out a little so thanks

@@rinovichaz3168 you're welcome and yes float will work better !

[@Strawhaty]

@@xodiaki surely your code would work without the miles? why use them??

Could you please explain RETURN in more detail please.

[@swallowedinthesea11]

Return value gets stored and saved into a variable. def addSum(num, num2): return num + num2 answer = addSum(500, 100) # answer = return 500 + 100 # answer = return 600 # variable answer is now equal to the return value 600.

[@koconutto]

I Didnt understand return very good

[@WhoForgot2Flush]

If anyone still needs helps, just think of a return as the value of the function. For instance at the end when he writes... km = convert(miles) you know the "convert" function will need to return something, can be an integer or a string or anything, because you are storing the returned value of the function to a variable. If you did not have a return in the convert method you would not be able to store it to a variable. Inside this function would be... return 1.6 * miles if you didn't put the return there it would still execute the code but you would not be able to say km = convert(mile) since the function would not be returning anything.

Very good video, very well explained, and I was able to do the miles to kilometers converter using just your explanation, thank you very much

[@pt-tutorials4293]

I love ur videos , but there is a question how did u know that after the print("ahhhh ahh 2" ) the function1 has ended

[@rickydawn6313]

What time frame are you referring to? If it's when he was defining function1, the function wasn't called so it's contents weren't printed.
