I'm a total beginner at Python and am currently running this nested for loop webscraping program to scrape for several Excel files for thousands of observations in my dataset. However, my code runs so slow in that I need to speed up this process so I can do this for 5-20 observations AT ONCE. People have suggested threading or asyncio, but I don't know how to use them or what code to write as the documentation online is extremely obtuse with no real explanation as to what Python 3.9 (Spyder) is doing during my trial-and-error process.

My code is LONG, but the main point is that I need to iterate over multiple elements i (in the first line of code) at once, but I don't know how to do so. I'm looking for an easy fix. I realize this code is very clunky, but processing power/speed is not an issue. Please only help me address the concurrency issues!

Here's my code. The very first line is the one that I need to iterate over multiple (10-20) elements in an array at once/concurrently for.

I am a relative novice to R & ggplot. I am trying to plot an interaction. When I plot the interaction using SPSS - the regression lines go from the y-axis all the way to the opposite edge of the plot:

However, when I use ggplot, the regression lines only go as far as the first and last data point which makes the graph look strange

Is there any way to remedy this and make my ggplot look more like the SPSS plot?

Here is the code I am using

I would like to know what the legal way of defining a constant struct that has a pointer as one of it's elements. Looking at this post (Initializer element is not constant in C) I can see the following:

6.6 Constant expressions

(7) More latitude is permitted for constant expressions in initializers. Such a constant expression shall be, or evaluate to, one of the following:

— an arithmetic constant expression,

— a null pointer constant,

— an address constant, or

— an address constant for an object type plus or minus an integer constant expression.

(8) An arithmetic constant expression shall have an arithmetic type and shall only have operands that are integer constants, floating constants, enumeration constants, character constants, and sizeof expressions. Cast operators in an arithmetic constant expression shall only convert arithmetic types to arithmetic types, except as part of an operand to a sizeof operator whose result is an integer constant.

My question is if the following is well defined according to the (intersection of the C89 and C99) standard. The contents of test.h:

I am new to modbus comunication, i have to read from an inverter a single value from one register using modbus protocol (i use python with pymodbus for this): From the inverter documentation i read about register documentation:

Register ADR: 31249 Description: Active power of system at PCC (W) CNT: 2 Type: S32 Format: FIX0 Access: RO

Well, i try my python script like this:

Given a small dataset as follows:

I am using the @Cacheable("MyCache") annotation along with the PCC (Pivotal Cloud Cache) provider.

Here is my configuration class

I know I am repeating myself in m JS code, its not DRY, though I am not sure how to write it in a more succinct way.

In order to change the style of elements on a click event, I follow the path of creating classes that contain the changes and then remove default classes and add new classes for the element being clicked on and then remove new classes and add default classes back again when the user clicks off the element.

Everything works 100%, though I am quite certain there is a much simpler way to do this by using some kind of loop and I am also not sure if I need all the constants I am using to hold the values of the object elements before the change - maybe there is a simpler way to access the DOM for these elements? (step 3.2 below).

I have only been learning web development for a month so I don't know what I don't know.

Can you take a look and let me know if you have a simpler approach?

I have 6 divs that share classes for a column, color, and content. They all look as follows:

I am trying to remove a number of properties from an object of objects I've found a lot of questions on stack overflow about doing this for array but I can't seem to figure out a clean way of going about doing this for my purposes.

My data looks like this:

I have a reduce function that formats my data in the way i need but the only issue is the data is nested inside an array. I need to remove the outter array or just stop the reduce function from adding it in but every attempt Ive made to stop the reducer from wrapping the data in an array breaks my code. Ideally I would like my reducer to not wrap the data in an array but if thats not possible removing the array i need from inside the reducer cleanly seems like the only solution:

my data looks like this:
