[@itishasan]

For those who didn't understand the static method, def is_integer(num) = Our Function & num.is_integer = Built-in Function. is_integer() is a popular built-in function that checks if a floating number is actually an integer. As an example, 7.0.is_integer() will return True whereas 7.3.is_integer() will return False. So as to avoid confusion, let's just change Our Function name to def check_integer(num) 🙂✌

I find myself especially loving the structure of this OOP tutorial, it comes from a Funtional programming aspect and gradually lead you into OOP with examples, as oppose to other tutorials where they directly introduce you to concepts like inheritence/settters etc.. This makes my understanding of OOP much more clearer and structred. Big thanks to FCC and the lecturer!

[@sancrosanct5070]

1. In the run validations to arguments part, if you aren't getting an error when you use an integer as the name, type in assert type(name) == str. This will not accept anything other than an integer as the name. 2. Make sure you have no spaces between the list in the items.CSV file. Its a minor thing but gave me a headache since I couldn't get past that for a while. Then do the normal int(item.get()) then it works fine. Finally most of the issues I encountered were as a result of not looking at the code long enough. If you encounter a problem, make sure to re watch the part where he DOS it and make sure you got it correct. This happened to me at the Len part and a few others. Finally if you encounter s problem not stated here, then copy the error and paste it in your browser. This shows a stackoverflow page first where you can figure out what's wrong. Hope this helps you and you don't have to go through the headache I did when solving those lol

1:08 "is_integer" is a float method, since the name of the written method and the float method name are the same, there is a misunderstanding as if the method is calling itself again. It was a confusing example. It took me a long time to understand and figure out what was going on. 7.0.is_integer() return True :)

Great tutorial. I was a bit confused when you built your staticmethod is_integer at first.

The is_integer function name almost confused me. is_integer is a method on its own in python so I thought you were calling your defined function inside the function itself.

[@ivanmendez3786]

Oh wow. I spent like 15 minutes trying to figure out the code. Thanks! 😅

Jesus, this was super confusing. I guess he could have called his staticmethod like "check_if_is_integer" to make a difference from the inbuilt function. Super awesome video anyways!

[@HereToSin]

@@StarFury2 1:09:00 One thing which you could also observe was that there were no parameters passed when calling the is_integer() {in line 45}, so no way would the is_integer method of the item class would be called, as that would require passing num parameter. But yeah, this was confusing at first glance!

[@user-iq1fg2um5k]

Я просмотрел все 2 часа этого курса, и научился читать код, и понял общие правила ООП. То что раньше было сложно понять, понимать стало гораздо проще. Вместо повторения \ дублирования кода, можно написать код лаконично, и он будет выглядеть очень аккуратно, это очень круто. Мне жаль что на просторах интернета, на Русском сегменте, вот таких полных курсов очень и очень мало, но найти ваш канал было просто волшебно. За 2 часа, начиная от самого простого, переходя постепенно к пониманию того что происходит, с указанием что откуда наследуется и передается, в общем я очень рад что эта информация очень полезна для меня. Осталось только научиться делать это самостоятельно, и продумывать код и его логику. Жаль у нас не было уроков программирования, да и преподаватели обычно не умеют доносить информацию понятным и простым языком, объясняя сложные вещи простым языком. Благодарю вас.

1:08:52 The name "is_integer" was a bit confusing because same method exists for 'float' class so in first IF statement num.is_integer() has nothing to do with the is_integer function that has been created in this code. That is_integer() method is pre-defined for the float class and that is only there to check if the num is a float or not and returns TRUE.

[@jimbowayoutub2]

@@akhilmachaan5010 Hi. The instructor added a static class to his Item class called is_integer() that returns True if num's type is integer and false if it's a float by using the isinstance() method built into python. But that alone would still interpret a number like 5.0 as a float just because it has a decimal. He wants his method to return True in such cases. Now because num is float he can call the is_integer() method that is *built into python's float class* ( same name but different function) One is created by Jim. The other built into Python's float class. Hope that helps.
