I have two data frames that look like this:

I've got lots of data and one of the columns is a free text description. I'm trying to process this in SAS and as part of this I want to correct some spelling and remove some words that don't really add any value to what the text is saying (aka 'stopwords').

I've got a way of doing this which is the code shown below, and this is working fine, but it means I need to have a line of code for each and every variant of a word I want to change.

In the example below I want to:

1. replace variants of the word "mug" (ie. "mug", "mugg", "mugs") with the work "cup"
2. remove three words that aren't really adding anything to the meaning of the text (called "stopwords", here I've just listed 3: "i", "me", "my").

To get this working I've needed to actually replace words surrounded by spaces (ie. replace instances of " mug ", " mugg ", " mugs " rather than "mug", "mugg", "mugs"). This is to avoid replacing parts of others words that contain that string of letters. So I've had to remove punctuation and add a space to the start and end of the string of text, before doing the spell changes, which is fine.

I'm sure there must be a better way of doing this than the code below and I'm keen to improve my SAS, so does anyone know a better way of doing this. Is there a way of creating a new list comprised of "mug", "mugg", "mugs" and then doing the replacement of all these words with " cup " in a single line?

Any thoughts would be greatly appreciated :)

I am trying to generate all possible ways to build a target string from source string in Python.

• source: cattcat
• target: cat

output: 5

• (cat)tcat
• (ca)t(t)cat
• (ca)ttca(t)
• (c)attc(at)
• catt(cat)

I try to calculate the date difference between second row and last row per group id. The data looks like

I have a dataset with each observation having two space-separated lists as string variables. I want a third variable showing the overlap between the string lists. Using another SO post, I've created a macro to calculate the overlap. I can't work out how to implement it in a DATA step to get the third variable.

This is my dataset, with dummy data:

I have these tables

The handleRemoveImgButn should remove the first image, but when I click the handleRemoveImgButn, the image is not removing from the DOM. I also tried setImgs((prevImgs) => prevImgs.filter(img => prevImgs.indexOf(img) !== 0, but it doesn't work. Below is the code. Thanks for any help in advance.

How can a function be applied on a pandas groupby that requires parameters from multiple columns of the groupby dataframe and returns two scaler values.

Below is the repeatable example. The last line gets the f_value
