in3 | The IN3 client | Storage library

I have some data, it looks like:

I have a dataset where I'm trying to make 3 graphs for the same variable (Den Volume) grouped by Species Group. I factorize the Species Group Column to control the order of the display, but the color order is not preserved between line and fill.

Here's the code snippet:

I ask user to insert an item name with extension ".txt" and if the item name is coresponding to the existing itemName.txt then user need to insert the location name with extension ".txt" where he want to "transfer" it . if everithing is ok then the content from itemName.txt will be writen into the locationName.txt

My Main looks like this :

I run the 'PuLP' solver on my OSx and after some conda updates it stopped recognizing the solver.

I call:

How can you define in Python3 a class MyClass such that you instantiate it like obj = MyClass(param1, param2) and then use it to compute an operation like res = obj(in1, in2, in3) ?

For instance, with PyTorch you can declare a model as mod = MyResNet50() and then compute its prediction as pred = mod(input).

Below is the code I tried. I declare a method and call it as obj.method().

I am trying to replicate the following type of SQL query that you can perform in SQL Server...the important part here is the WHERE clause: Select InventoryCD from InventoryItem WHERE InventoryCD IN ('123123', '154677', '445899', '998766')

It works perfectly using the IN3<> operator and a series of string constants: i.e. And,

However, I need to be able to do this with an arbitrarily long list of values in an array, and I need to be able to set the values dynamically at runtime.

I'm not sure what type I need to pass in to the IN<> statement in my PXProjection query. I have been playing around with the following approach, but this throws a compiler error.

I have a class with an overloaded constructor where each version of the constructor initializes a different set of private attributes for that class. I also have a public member function of that class that will perform some operation based on the private attributes of that class. I want to overload the member function so that when I call it from the main function, it will execute an operation and return a value. Each operation will be different based on the exact outcome of the corresponding constructor. Is this possible? How could I implement this in C++? This is some incorrect code trying to express the idea:

I want to obtain new values for each step and use them inside an equation for further steps. Normally, I can perform loop but for this problem, I need to use past values, too. For instance, I have flow data like this:

For example, this code:
