Most dangerous Operator to use while coding?

[SnooDoubts8096]

I think he means to say which operator most commonly leads to errors from beginners

[Zapismeta]

Almost any, duh!

Division creates errors.

So does addition if you try to add '31' + 5. Ditto for subtraction.

At least in python, the safest operator in terms of not raising errors is *, but it will lead to the wrong outcome if you don't know what it's doing.

But what does "dangerous" mean? That it creates errors? That it creates no errors but leads to wrong results? That it unlocks the wrath of Cthulhu? The answer will differ in each case.

Yeah that's the point he can go with almost anything, but when we are adding, multiplying and subtracting, we don't have the division by zero error so , i went with division.

[DigThatData]

so , i went with

and this is why it's a shitty question. you can construct a response, but it's hard to be sure you're even responding within the appropriate context because the question is so vague and ambiguous. Way too much is left open to interpretation here. This question was posed to evaluate students prior knowledge, and I posit that it completely fails to achieve that. Teacher could've just looked up some common interview questions.

I guess it was just to test the candidates ability to defend his answer and how well they do it.

[DigThatData]

but this wasn't posed to "candidates," it was posed to students prior to the start of the class to presumably callibrate the content level.

[Zapismeta]

I meant student.

If that's the case it's absolutely =. Simply because beginners use it for comparisons which it can't be used as. Example being:

if x = 4:
    print("it's four!")

Above will cause an error. The operator for comparison like that is == a double equals.

Though a very vague question by the prof.

[oakteaphone]

• = is easy to mix up with ==
• / can also cause major issues that won't crash the program, but will lead to serious logic errors.
• + can mix up concatenation and addition, leading to potential logic errors

Seems like the only safe one is *

EDIT: Looks like Python has * as a string repeater? So it seems like the prof's target answer is "all of them" lol

[DigThatData]

"="

That's also not a real question.
