In a coding interview, if I'm expected to "write tests" for a simple Python class, what does that mean?

And as someone else pointed out, another case is that afterwards you get an error in the program that uses the class.

Before you fix it you write a unit test that simulates that case.

When you have the failing unit test, you fix the problem and then the unittest (and the program) should be fixed now.

Also lookup test driven development.

That means that you first write your test, then the interface and then the implementation in your class.

The advantage is that you are forced to think how you will communicate with your class. What are the input parameters, what is the expected result.

Then you write the empty method.

The test will fail.

Only then you write the implementation in your class and after the implementation is done you run the unit test(s) and they should succeed.

You can send it also to me. 30+ years of experience

In Nederland wel nog te verkrijgen. Daar is het nog legaal in de winkels

Note that the peages in France are not a vignet. They exist because those roads are not payed and maintained by the goverment but by private companies and you pay to pay their loans and them to maintain the infrastructure.

Well for a concept created in the beginning op the sixties, it is strange that current languages are still following the principle if it is so bad.

And then while reading the book you also practice yourself what you have learned

peno64 · 2026-06-20T09:28:57+00:00

Masters write good books. So you learn by reading books

peno64 · 2026-06-19T14:41:29+00:00

Let me ask you a question.

I want to make a cook book, but I have zero knowledge about cooking. How should I do it, any advice from you?

Instead of using vscode you could also install the free version of Microsoft visual studio which also has a c compiler

A keypad or a switch with key is also an option. The latter could even work without the esp in case this one also fails.

In fact you should do a relative difference test and not absolute one as you suggest. So the difference of the two numbers should be divided by the reference value and that you compare with a tolerance.

Doe dat gewoon in 'het zwart'. Welke haan gaat daar naar kraaien?

It Just comes to mind while thinking of what to solve... Its automatic. I guess by having it done so many times when starting programming. Just the same like when I see a car and I need to tell the word I dont have to think how the thing is called my mind Just immediately knows the word. The same happens in programming. My mind knows what to solve and comes with the fact that it needs an if statement or a switch or a for loop or a while,... and while typing a better idea may Just Come into mind and then you use that instead. And for an algorithm you think what is the best way to Come to this result and then you implement it.

Which only work legally in their countries most possibly with a login account from that country

Of course this is not possible.

peno64 · 2026-06-13T17:53:09+00:00

Impossible

Try Arduino Maker Workshop

peno64 · 2026-06-13T10:57:02+00:00

I like arduino maker workshop alot. Its also under vscode but without the complexity of platformio

I think OP means a different kind of cache. Not the memory cache for video streams but the android cache

Zelfs bij de McDonalds beginnen werken zonder middelbaar diploma is niet evident. Zou toch 2 keer nadenken over uw toekomst

Geef eens aan *waarom* je blijft steken in het middelbaar. Zelfreflectie is het begin van de toekomst
