I am working on getting some data, and as I am getting this data in a list, I want to write it into a csv file (maybe using pandas)

The data I want to convert is in the form of list:

In response to some comments received, here´s what I am trying to do:

1. Replicate an XLS formula that works fine. The below is the beginning of what that XLS formula does
2. The complete XLS formula basically interpolates input variables along a time horizon (say 120 months). For example if you ONLY input mo 1 (along vector_1) = .25 (along vector_2), mo 2 (along vector_1) = .50 (along vector_2), XLS outputs mo 1 = .25, mo 2 = .50, mos 3-120 = 0. If you ONLY input mo 1 = 2 and month 3 = 4, then XLS interpolates and output is mo 1 = 2, mo 2 = 3, mo 3 = 4, mo 5-120 = 0. If you ONLY input mo 3 = 2, then output is mo 1 = 2, mo 2 = 2, mo 3 = 2, mo 4-120= 0. Etc. This R snippet is only the beginning of this formula
3. So all I am trying to do below, for now, is assign vector_2 variables along the mos 1-120 time scale, and if the current period in time horizon (vector_1) > period in the 1-120 scale, then a 0 value is returned.

I was worried about posting this, this is difficult to express clearly. And I want to learn enough to be able to do the rest of this on my own. Best way to learn!

I´m new to R and come from Excel/VBA world. I´m slowly converting an Excel formula to R equivalent. Will eventually change this to a function and explore using SEQ instead of this FOR loop. But for now, what am I doing wrong with the below? I don´t understand why I get NA in the 5th position of the output vector and 9 output elements instead of 10.

I need to restructure an XML into 4 distinct 'blocks'. The final block must include a distinct value from a group-by and the position of the first and last instance within that group. As I am grouping the data to build the other blocks I cannot find a way to achieve this.

I have the following dataframe

The Have two filters that will allow a user to chose a major command or grade. However, can someone point me into the right direction on how to actually have them listen to each other. for example, if the user pics a 30ABCT and wants to filter that by the grade of E4. What is the way I need to do that?

I have 2 tables,

• Products
• Categories

When I query SELECT * FROM categories, I get this:

Okay, so. I have a slideshow on a page of my website. It's supposed to be in one column of my website. The images conform to the column just fine, but the buttons for "next" and "previous" do not. I want them to be on the left and right sides of the column they slideshow is in, and preferably centered vertically as well.

Bonus: Is there any way to make the next and prev buttons circles?

Here is a mock-up of what I'm envisioning for this page.

And here's my code:

I'm currently doing CS50 and I need to write a little html page inserting interactive elements from Javascript.I'm a total beginner with this language and I'm trying to find out how to display an image when I hover on a text. Apparently there's almost zero topic about this on internet, I've only found this,which does work but only with the first image.The reason is because the "id" is the same for all the urls,I get that,but how can I modify the code so that it can work for all the different texts/pictures?I kind of get the whole picture because I know Python but html and Js are brand new to me.Any help would be appreciated,thanks

I have on website navigation and I would put in image. If i enter image code the image will on the end, and I want if the image be on start navigation (before Link 1). Here´s my code with CSS:
