If a programming language allows something, doesn't automatically mean it's a good idea to do!

@pawjast @matplotlib Right, matplotlib is awesome once you get the hang of. The gallery especially is both helpful and impressive.

@CodingComputing @matplotlib I see your point but. But i honestly think these days Matplotlib has one of the best documentation for an open source project so once you've found the function you're looking for, there will be a clear explanation and plenty of examples waiting for you.

A bug is when code output differs from intended output. To find out why so... You need to know *exactly* what the code is doing. That's the only solid way to diagnose.

When you look at small chunks of code, ask yourself: - What is this code supposed to do? - Which parts looks tricky? - How does it do what it's supposed to do? That helps to properly understand the code going forward.

Debugging isn't about changing code. It's about finding what to change.

Solving bugs expands your capabilities. Because you improved on something you messed up before.

I would try to write "optimized" code from the very start of the project. I had the attitude "If we are doing it let's do it right". But my concept of "right" was wrong. Clarity is the right target to shoot for at the start. Not optimization.

Most important reason to be careful of AI: It tells you what it thinks you would like to hear. And that most often is that you're absolutely right.

Why wait to clarify specs when I can code right away? Try: - Take up a specification - Write code tailored for it - Polish and optimize - Now change to another specification - Wonder if you should scrap & rewrite the whole thing Pain. Avoid.

Multiplying a string with int:

Coding Computing Coach@CodingComputing

@PythonPr Answer: D 9999 Solution: Observe that '9' is a string, not an int. b is an int 4. So, a * b is a multiplication of string and int. Sounds strange, but this is just repetition of the string. So, '9' * 4 is the string '9' repeated 4 times, ie, 9999 that's what gets printed.

Do you doubt whether python sneakily changes variables?

Coding Computing Coach@CodingComputing

@PythonPr Answer: B) hello Solution: On the surface it looks trivial. s is initialized 'hello'. t is assigned s. s is modified to upper. So it 'HELLO' now t is printed. What is the value of t? t hasn't explicitly been changed, so it's going to the initial 'hello'. But you might +

@PythonPr s now references a different object than before. This wasn't a mutation where s references the same object, but the object itself has changed. So, what about t? t still references the original object, which hasn't changed at all. Therefore, the value of t is 'hello'.

English

Coding Computing Coach@CodingComputing·30 Ara

@PythonPr s.upper() s.upper cannot modify the existing object 'hello' because it's immutable. So, s.upper() has NO CHOICE other than create a new string object 'HELLO' and return it. The returned object is referenced to s via `=` s = s.upper() So this was a re-assignment, ie, +
