PowerGrid | GPU accelerated non-Cartesian magnetic resonance imaging | GPU library

I am writing a code for downloading the historical data for multiple stocks. The code is as given:

I have a dataframe which looks like this:

I have the following multiindex dataframe:

i'm trying to get my python program to insert data into MySQL and i followed a guide however i keep getting the error below.

"Authentication plugin '{0}' is not supported".format(plugin_name)) mysql.connector.errors.NotSupportedError: Authentication plugin 'caching_sha2_password' is not supported"

have i missed a setting in mysql server or does python not support this yet?

I think i can just change the password type but mysql doesn't want to let me for some reason all users with caching_sha2_password can't be changed and when i create a new user and select SHA256 Password I get the error creating account @% the password hash doesn't have the expected format. check if the correct password algorithm is being used with the PASSWORD() function.

How can i get rid of the quotes in the output. I have tried to used .strip('') but the output does not seem to change.

I have a d3v4 force-directed graph. For simplicity's sake, let's assume it's like this.

The graph shows flows (like a powergrid). I'd love to be able to animate each link to show flow from the target to the source (with moving dotted lines, bubbles, something).

Does anyone have an idea on how to do that?

I'm working on a "simple" game for fun kinda like Factorio, but not grid-based. Now I need some kind of system to keep track of all my different building-types and to let the player pick a type in a menu. The menu is handled by the UI class and that class calls methods in the Game class to check against money and whatnot. The Game class then calls the World class to add whatever building the player selected. At least that's the relevant bit, I think.

As I have it now, to store the different building-types I have a class named BuildInstruction with sub-classes BuildingBuildInstruction and ConnectionBuildInstruction. These classes simply holds Action<> thingamabobs that returns a building / connection when given world-coordinate / two connection-points.

I've run in to some problems with this method though both in the Game- and IU-class. I can't seem to divide the work between the classes in a logical fashion...

I know this is a ridiculously vague question but it's kinda hard for me to formulate. Basically, it would be awesome if someone knew of some sort of common practice for these sorts of things... I'm open to all suggestions.

Thank you!

And BTW, here's some code if it helps to understand:

This is what I use to pass options in a sort of hierarchy to the menu:
