sux | Succinct data structures in C/C | Data Mining library

Here is the data I am working with:

I've got a series of malformed JSON data that I need to use Regex to get the data I need out of it, then I need to use regex again to remove a specific aspect of the data i.e. the main category, in the example below it's 'games'.

Part 1 works, the second part does not.

I've limited experience with Python, and next to no experience with Regex.

Final Output: games

I'm getting the error:

ValueError: pattern contains no capture groups

The series of data contains information formated like this:

I have a large data frame that contains an alphanumeric character variable, specifically it contains information on breed composition, from which I need to create covariates of breed fraction.

The breed composition column contains over 7000 combinations of breeds and is of varying length (i.e. some animals have 2 breeds, some have 10). The breeds are always identified by a two letter code and the fraction of that breed is the coefficient that follows it divided by the sum of all breed coefficients (coeftotal) for that animal.

I'm looking for a method to take the coefficients from this variable (breed) and make covariates corresponding to proportions of 7 specific breeds (SU,DP,RV,RI,CD,PO,HA). There are many more breed codes present in the data and some animals may even have none of the breeds of interest. The data frame contains over 1 million records, and I have not been able to find an efficient solution to my problem that does not involve an endless number of grepl /if else statements for each specific breed code and each coefficient of interest (ex. SU1 to SUx). Furthermore, the problem is complicated by the fact that the coefficients do not sum to the same number. An example of my dataframe and the desired output is below. Any ideas are appreciated!

I'm using ComputerCraft, a Minecraft mod that adds computers, monitors, modems and so on, which can be programmed using Lua scripts.

While running my script I get this error: "bios:171: bad argument: string expected, got nil".

I dont understand because it says line 171 even though my code doesn't exceed 30 lines.. Can somebody explain?

I have two tables which contain the product information of Type1 and Type2 and one common table which has rate information.

Consider the following table structures

Table #1 Type1Product:

I'm attempting my first project in Java after learning the basics, so I apologize for what is likely a complete beginner question. I have been searching all afternoon for assistance, and my code is starting to look messy and broken.

I am attempting to create a dice roller that rolls a number of d10s, then proceeds to check how many are 7's or above and count/display them as successes. If none of the rolls are a success, I want it to display "Botch".

After some research, I found creating an ArrayList and going from there was (what seems to me as) the best option. But I've been stuck for some time now, with different errors and issues coming up, and each time I take one down, the code gets more confusing and my goal seems farther away. My buddy said "welcome to programming" and suggested I ask the community.

Here is what I'm working with:
