Why does decimal.Decimal(0)**decimal.Decimal(0)
not return 1 but an error?
ANSWER
Answered 2022-Mar-06 at 16:44Python's decimal
module follows the IBM General Decimal Arithmetic Specification, which says that 0 to the power of 0 raises an Invalid Operation condition and produces NaN. By default, Python raises a decimal.InvalidOperation
exception for Invalid Operation conditions, but you can change the context settings to get the NaN if you want:

QUESTION
I'd like to start by saying that I'm very new to Python, and I started this project for fun.
Specifically, it’s simply a program which sends compliments to you as notifications periodically throughout the day. This is not for school, and I was actually just trying to make it for my girlfriend while introducing myself to Python.
With that in mind, here's my problem. I started this project by writing the simplest version of it: one you have to start each time your computer loads, and runs while you're actively using the computer. This portion works perfectly; however, I can't seem to figure out how to do the next step: have the program carry on as normal after reboot and save its progress.
I know how to get it to start up again after reboot. Still, I'm not sure how to save its progress. Particularly, since I'm pulling the compliments out of a text file, I'm not sure how to have the program save what line it's on before rebooting. This is needed as I don't want the program to start from the first compliment each time, as there are over 300 unique ones as of now.
In order to help you understand where my code currently is as for the best advice, I've shown it below:
...ANSWER
Answered 2022-Jan-10 at 13:42Well, you should save an index to a file or something before program shutting down.

I am high school math teacher who is teaching myself programming. My apologies in advance if I don't phrase some of this correctly.

QUESTION
I'm trying to implement a unique_ptr class in C++, but how to know if the pointer we passed to it was allocated with new
or new[]
without using default_delete
(my school standard doesn't allow c++11).
I mean when you pass your pointer to the constructor like this for example:
ANSWER
Answered 2021-Oct-24 at 08:01You can't tell. And neither can std::unique_ptr
.
Think about it. If it could be determined automatically, you wouldn't need two kinds of delete
.
std::unique_ptr ptr(new int[10]);
is wrong, since it will call delete
, rather than delete[]
.
Use std::unique_ptr ptr(new int[10]);
instead, which will call delete[]
, rather than delete
.

I need to make a OMR detection system using Python for my High School Vacation Project(which potentially might be used by the school to some extent if it is reliable enough) , I have done quite a bit of research on it , and have tried out everything from contours to template matching, I feel template matching works fine but it can only detect one circle out of many in the OMR sheet, can someone help me in figuring out how I can detect multiple(all) circles(irrespective of whether they are bubbled or not), in the omr sheet and their respective coordinates , that would be enough for me.

Install school
You can use school like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
