kandi X-RAY | DocTest Summary
DocTest is an experimental tool for testing Swift example code in documentation. DocTest is inspired by Python's doctest. The hardest part of software documentation is writing it in the first place. But once you clear that initial hurdle, the challenge becomes keeping documentation correct and up-to-date. There's no built-in feedback mechanism for documentation like there is for code. If you write invalid code, the compiler will tell you. If you write valid but incorrect code, your test suite will tell you. But if you write documentation with invalid or incorrect example code, you may never find out. DocTest offers a way to annotate Swift code examples in documentation with expectations about its behavior, and test that behavior automatically — just like a unit test.

QUESTION
I am an amateur Python coder trying to find an efficient solution for Project Euler Digit Sum problem. My code returns the correct result but is is inefficient for large integers such as 1234567890123456789. I know that the inefficiency lies in my sigma_sum function where there is a 'for' loop.
I have tried various alternate solutions such as loading the values into an numpy array but ran out of memory with large integers with this approach. I am eager to learn more efficient solutions.

Define G(n) to be a dictionary. Its keys are integers representing digit sums and its values are the sum of all positive integers < n whose digit sum is the key. So
QUESTION
Can someone help me understand how I can identify differences between the actual and expected output when performing a doctest? In the below, the expected and actual output looks identical eye.
I'm pretty sure there is some white space error since when I add optionflags= doctest.NORMALIZE_WHITESPACE in the doctest, the test is successful. Is there another flag that can help a user triangulate on the location of such a whitespace error?
ANSWER
Answered 2022-Jan-22 at 19:58Try using the flag REPORT_NDIFF. The docs say, "This is the only method that marks differences within lines as well as across lines", which will help identify any whitespace problems, for example:

QUESTION
I am a beginner in documentation with Sphinx. I wanted to produce numpy style documentations. Therefore, I used numpydoc extension. Numpy uses pydata theme, however I chose furo. I understand that there will be some differences in appearance, but I expected my page to have the same format as numpy's at least, though I get the parameter names, and types capitalized. Descriptions are not capitalized.
My docstring:
...ANSWER
Answered 2022-Jan-02 at 17:47Note: The issue has been fixed in Furo 2022.1.2.
It's definitely the theme. Probably an oversight, or even a bug, as Furo shouldn't change capitalization of identifiers and types in the API documentation. But it does, here, by applying the CSS property text-transform: uppercase.
You can override it with a custom style. In your docs folder, create a subfolder style, and in it a file custom.css with this content:

I'm trying to compile a file that makes use of Python's C API. I'm working in a conda enviroment, running on macOS Monterey. I'm compiling using GCC as following:

Answered 2022-Jan-01 at 06:20This command: gcc file.o -o a.out does not link to a python library.
You need to add (append) -lpython3 and possibly -L${CONDA_PREFIX}/lib/python3.9 to it.

For one python project, I want to ship a data file with the package. Following various (and partially contradictory) advice on the mess that is Python package data, I ended up trying different things and got it to work locally on my machine with the following setup.
My setup.cfg contains, among other things that shouldn't matter here,
ANSWER
Answered 2021-Nov-24 at 20:32You almost did it right, try slightly update your MANIFEST.in to any of the following examples:
include src/lexedata/data/*.ziprecursive-include src/* *.ziprecursive-include **/data clics3-network.gml.zip
As you can find in docs include command defines files as paths relative to the root of the project (that's why first example starts from src folder)
recursive-include expect first argument being as dir-pattern (glob-style), so it is better include asterisks

I have 3 files in my directory "project": doctest.h - the testing library, doctest_main.cpp - a file needed for the library, and tests.cpp - the file with tests.

QUESTION
I am looking to use doctest formatted examples for an abstract (ABC) or Protocol class without having doctest fail because the methods of the class are not implemented.
The docstring and example is supposed to reflect the general use case of multiple implementations of the abstract class and I would like to keep the doctest format for consistency.
Any idea for suppressing the doctest for a single docstring or for all abstract or Protocol classes is appreciated. I know I could also write is as a Sphinx code block but it wouldn't be as human readable in the code in my opinion.
Example:
...ANSWER
Answered 2021-Nov-08 at 00:12Your doc test has to do the same thing a user would be expected to do: define a subclass that implements do_something and instantiate that class.
QUESTION
I am having a very strange unit test failure in Python 3.9 doctests. Normally I'd have to sanitize my problem, but this is in pretty low level code so I can post it here in its entirety.
I can run this doctest in Pycharm without issue. When I run it on the command line, I get a failure that makes no sense. Any help would be appreciated.
quadratic_solver.py
...ANSWER
Answered 2021-Sep-16 at 16:10The problem here is the line doctest.testmod().
PyCharm just detects that there are doctests in the Python module, and runs them using its own doctest runner, so it just ignores that line.
If you call the doctester from the command line, it does basically the same: it detects all doctests and runs them, but additionally it also tries to doctest the doctest execution line. You can see this if you use verbose output:
