1. question_data is a list.
2. question_data() calls this list.
3. It's impossible to call a list (what would it mean to call a list anyway?), so you get the error.

Simply don't call the list:

NVARCHAR(n)

Code language: SQL (Structured Query Language) (sql) In this syntax, n defines the string length that ranges from 1 to 4,000. If you don’t specify the string length, its default value is 1.

(emphasis mine)

So your NVARCHAR is interpreted as NVARCHAR(1) which means it can hold a string of only 1 character. Your string "Iron Maiden" is truncated to the first character, "I".

Use of a Func factory parameter would sort this out.

You are calling check_answer, which tries to read self.user_r, before you have called next_question, which writes self.user_r.

Here is a way you can avoid calling check_answer before you have called next_question:

1. $unwind - Descontruct score array field to multiple documents.
2. $group - Group by null (for all objects), next $sum for the $size of score.catches.

To avoid $unwind if you want to get the total for each document, you can use this aggregation stage:

In getAvailableOptions, the indexOf you are using results in performing a Strict Equality Comparison on objects, thus comparing by reference. Since your values come from two different arrays that were instantiated separately, the references will be different for an identical question.

A possible solution is to use find instead and to compare using the question's value:

You can combine the text together as one string and extract the values based on pattern in the data. This approach will work irrespective of the line number in the data provided the pattern in the data is always valid for all the files.

This in no way a complete answer. I assume you don't want to map/create classes for each "sub class", e.g. Barbarian, Wizard etc. You could perhaps use JsonConverter. The example only handles the first "anonymous" range of objects. Maybe you'll find some of this useful.
