Why is ‘==‘ coming before ‘in’ in Python?

由 时间秒杀一切 提交于 2021-02-20 06:42:32
问题 The following code outputs False, when according to the Python Order of Operations it should output True (the order should be in -> ==, not the other way around). Why is == coming before in? y = "33" "3" in y == True Output False 回答1: The existing answers give helpful advice that you shouldn't compare booleans to True because it's redundant. However, none of the answers actually answer the root question: "why does "3" in y == True evaluate to False ?". That question was answered in a comment

How can I conditionally execute a module-level doctest based on a feature flag?

由 試著忘記壹切 提交于 2021-02-20 06:40:26
问题 I am writing documentation for a module that has some options controlled by a Cargo feature flag. I'd like to always show this documentation so that consumers of the crate know that it's available, but I need to only run the example when the feature is enabled. lib.rs //! This crate has common utility functions //! //! ``` //! assert_eq!(2, featureful::add_one(1)); //! ``` //! //! You may also want to use the feature flag `solve_halting_problem`: //! //! ``` //! assert!(featureful::is_p_equal

SLIME on Emacs with paredit in repl - how to prevent execution of incomplete but balanced expressions?

由 时光总嘲笑我的痴心妄想 提交于 2021-02-20 06:38:46
问题 I use paredit on emacs with SLIME's repl. This means that at any point during my typing on the repl, my s-expressions are balanced. However, they may not be complete, and I might want to continue typing inside them in another line, as follows: CL-USER> (defun print-hello () ) When I start a new line by pressing the enter key, however, the SLIME repl executes my incomplete expression. I want it to wait for me to complete the expression, as follows: CL-USER> (defun print-hello () (format t

问题 If I convert a single quote ' from HTML to Markdown, it is automatically escaped: % echo "'" | pandoc -f html -t markdown \' I'd like it to output without the slash, as it makes text with contractions rather much harder to read. I thought this might be due to the "all_symbols_escapable" option, but it still happens, even when I turn that off: % echo "'" | pandoc -f html -t markdown-all_symbols_escapable \' It isn't a problem, however, for markdown_strict: % echo "'" | pandoc -f html -t

How to fill contours that touch the image border?

由 本秂侑毒 提交于 2021-02-20 06:35:29
问题 Say I have the following binary image created from the output of cv::watershed() : Now I want to find and fill the contours, so I can separate the corresponding objects from the background in the original image (that was segmented by the watershed function). To segment the image and find the contours I use the code below: cv::Mat bgr = cv::imread("test.png"); // Some function that provides the rough outline for the segmented regions. cv::Mat markers = find_markers(bgr); cv::watershed(bgr,
