QUESTION
Sometimes I find myself needing to initialize an object with a property that matches the property of another object. When the property name is the same, I want to be able to use shorthand syntax.
(For the purposes of the examples in this question, I'll just keep the additional properties to a tag: 1 property, and I'll reuse message in subsequent examples as the input/source of the information. I also indicate an extra unwanted property of message because I'm cherry-picking properties and do not intend to just use Object.assign to assign all the properties of message to the result.)
ANSWER
Answered 2021-Jun-15 at 16:26The best I have so far is
{ person: message.person, tag: 1 }.Is there shorthand initializer syntax to achieve this?
No, this is still they way to go.
hoping that a property name would magically be inferred from
person

I wanted to make a monthly report with sumifs with 2 conditions like the image above. But all I got was errors.
Code I am using
=sumifs(D2:D13;D1:G1;C16;B2:B13;or(B2:B13="apple","cherry","watermelon"))
ANSWER
Answered 2021-Jun-12 at 06:30You may use combination of multiple sumifs to solve your calculation since you won't know which will be the first row item that has market value and sum of amount of other fruits will return 0, therefore the calculation will still give correct total.

QUESTION
This is not a Duplicate question, I spent 3 days searching here and there is no other question similar to mine!
This javascript generates random words only when called from one single div, or the first one when trying different DOM Methods to get Elements.
I've tried several options and combinations with getElementsBy ID, Tag, Name, Class, and CSS Selector.
However after several days searching and testing, I can't make it work in more than one div.
I need to use the same array as the only source for all my 36 divs, to generate random words from an onClick event on each of them.
I'm open to edit it, or completely change it.
This is what I have currently working for the first div using getElementsByClassName which I suppose should be the correct way as I need to call this script from several elements, not just one:

Say I am building a record type:
...ANSWER
Answered 2021-Jun-06 at 18:50Regarding the last error, it's because OCaml requires a 'stable path' to types inside modules so it can refer to them. A stable path is a named path to a type, e.g. Fruit.t.
By contrast, StrEnum(struct type t = ... end).t is not a stable path because the type t is referencing a type t in the module literal which does not have a name.
Long story short, you basically can't skip defining the variant module separately. But it's simple to do it in two steps:

QUESTION
I am using pandas to import a dataframe from excel in order to sort, make changes and run some simple addition and division on the data.
My code is working but it has global variables throughout. I think this is poor practice and I want to somehow eliminate these global variables but I am confused on how I can go about doing this.
I'm not sure how I can further modify my dataframe with indexing and slicing without declaring global variables.
...ANSWER
Answered 2021-Jun-07 at 06:55There are several things you could do, dependent on the overall structure of your code and your goal. Without knowing more about your case and, for example, seeing how the snippet you provided is embedded into the rest of your code, those are only possible solutions.
You could define a function, make it take a dataframe as an argument, perform operations on it and then return the modified dataframe. The function could also simply take a filename as argument, so that the respective df is created within the function to begin with. If you do not need to refer to intermediary variables such as new_indexes or sliced later in the code, using a function to perform the operations might be a good way to go.
You could also define a Class, make the variables into properties of objects of that class and write methods to perform the respective operations you want to do. This would have the advantage that you could still access your variables, if necessary.
QUESTION
I am using the following code to scrape content from a webpage with the end goal of writing to a CSV. On the first iteration I had this portion working, but now that my data is formatted differently it writes the data in a way that gets mangled when I try to view it in excel.
If I use the code below the "heading.text" data is correctly put into one cell when viewed in excel. Where as the contents of "child.text" is packed into one cell rather then being split based on the commas. You will see I have attempted to clean up the content of "child.text" in an effort to see if that was my issue.
If I remove "heading.text" from "z" and try again, it writes in a way that has excel showing one letter per cell. In the end I would like each value that is seperated by commas to display in one cell when viewed in excel, I believe I am doing something (many things?) incorrectly in structuring "z" and or when I write the row.
Any guidance would be greatly appreciated. Thank you.
...ANSWER
Answered 2021-May-05 at 06:03csv.writerow() takes an iterable, each element of which is separated by the writer's delimiter i.e. made a different cell.
First let’s see what’s been happening with you till now:
- (heading.text, child.text) has two elements i.e. two cells, heading.text and child.text
- (child.text) is simply child.text (would be a tuple if it was (child.text**,**)) and a string's elements are each letter. Hence each letter made its own cell.
To get different cells in a row we need separate elements in our iterable so we want an iterable like [header.text, child.text line 1, child.text line 2, ...]. You were right in splitting the text into lines but the lines weren’t being added to it correctly. Tuples being immutable I’ll use a list instead:
- We know heading.text is to take a single cell so we can write the following to start with

Answered 2021-Jun-05 at 13:07It is very disappointing that eqn does not allow a new mark to be set. Here is a poor workaround that might be of some use. It consists of repeating the first equation but with the keyword mark in the new position, and diverting the output to nowhere so it does not appear. .di is a base troff to start and end a diversion.
