I have an Excel file that I can successfully read in Spyder using the library pandas

The problem is that I can't extract specific elements from df as I would expect from a NumPy.ndarray (isn't it the type that the function as_matrix() return?)

For example :

How could you get the row-wise frequency of equivalent combinations of elements (partitioned as fixed sets of columns) in a table?

Say I have a table with rows of the form:

I have a dataframe with about 60 columns and the following structure:

I have a single class in Intersystems Cache that

1. writes records on the globals based on the user calling it
2. Iterates on the globals and places results on a string
3. Writes the said result to a notepad file via FILE

However, a part of the code always returns error.

A search in their documents reveal :
The routine has too many nested calls to Do, For, Xecute, New, or user-written functions.

If you are wondering why I use a single class, which violates SOLID, it is because when I try calling other methods via ##class() in a method I am met with the error . Hence I took the code inside the methods that I need and mixed them in a single method.

Is there a way to call a class METHOD inside a CLASS properly?

About the FrameStack error, Exactly how many is too many? how do I avoid this?

EDIT : code as requested
