QUESTION
I want the following output to get aligned properly in the form of a table:
My attempt: I created a class with member function(a function to display the products available in a store) and member variables. Then in the main function I initialized all the member variables and passed control to the user defined function to provide the output. I have provided some code snippets to support my idea.
...ANSWER
Answered 2021-Apr-13 at 10:28By default when setw is set, << operator uses right-alignment.
By printing TAB characters the right-alignment is broken and the rest of the line gets shifted.
Try to avoid using \t in combination with setw, and set alignment to left in the beginning:
QUESTION
I'm currently trying out ParlAi by following the quickstart from the documentation. I already installed ParlAi and currently on "View a task & train a model" but when I run the code parlai display_data --task babi:task10k:1, I got these tracebacks instead.
ANSWER
Answered 2021-Feb-13 at 10:40Yes, these tracebacks indicate errors. The kinds of errors here are pkg_resources.ContextualVersionConflict which is kind of confusing because they don't have Error in their name. For these traceback blocks the last line is the error, the second to last is the way the error was raised.
pkg_resources.ContextualVersionConflict: (urllib3 1.25.8 (c:\users\dean\anaconda3\lib\site-packages), Requirement.parse('urllib3~=1.25.9'), {'parlai'})
Shows that you urllib3 is at 1.25.8, but it needs to be between 1.25.9 and 1.26.
pkg_resources.ContextualVersionConflict: (Sphinx 2.4.0 (c:\users\dean\anaconda3\lib\site-packages), Requirement.parse('Sphinx>=3.0'), {'sphinx-autodoc-typehints'})
means that your sphinx is 2.4.0 but should be greater than or equal to 3.0.

I created some code to add some text depending on the language found in the link but I have a problem with matching exactly the language because the pattern is too simple. I need to find exactly what comes after .com and nothing else. I tried this /.*\/\/.*?\/(\S{2})/gm expression but, it isn't exactly what I'm looking for.

How it worksWe are iterating trought all values of the langs object using .map
langs.map(e => ...)We are checking if the langs pattern + Regex matches the URI using
findUrl.match(new RegExp(..com${e.pattern}., "g")We extract the matching value from the array using
.filter(e => !!e).pop()
QUESTION
I'm creating a small thing for practice with JavaScript and I get an error which I can't understand why is happening.
The browser (chrome, firefox) gives me the following error message in the console: "Uncaught TypeError: Cannot read property 'querySelectorAll' of null at script.js:12", but when I try the code in JSFiddle everything is working as expected. JavaScript is allowed in the browser, so normally it should work fine.
According to HTML DOM querySelectorAll() Method normally, the browser should display correctly the code.
The other question is: How can I avoid typing so many if's? If I want to use a JavaScript switch, how should I write it?

Answered 2020-Sep-09 at 21:46You can avoid all the repetitive code using an array of objects.

Hope you're well. I need your help today.
I've got on my page a which contains attributes. One of these, named data-params, contains an object. In this object we've got a lot of data and I want to get only one value. I tried to use Object.keys OR element.attributes but it doesn't work. I really don't know how and where to search. It seems this object looks like JSON.
By the way thanks a lot by advance for your help and happy coding :)
