I am working on a React Web Application Where I fetch and display student data from an API and I keep getting the error,

Warning: Each child in a list should have a unique "key" prop. Check the render method of Accordion

Accordion.js being one of my components of my Web Application

Any Help to fix this issue would be appreciated :)

I have tried passing a key prop with an id to the Accordion component from a parent component, but that did not seem to work. Could it be that I need to pass a key in my test score paragraph?

How to publish two messages of the same type to different worker instances based on the message content without using Send and RequestAddress?

My scenario is:

I am using Azure ServiceBus and Azure StorageTables.

I am running two different instances of the same worker service workera and workerb. I need workera and workerb to both consume messages of type Command based on the value of Command.WorkerPrefix.

the Command type looks like:

I want to add a new column 'BEST' to this dataframe, which contains a list of the names of the columns which meet these criteria:

• Subtract from the current value in each column the value in the row that is 2 rows back
• The column that has the highest result of this subtraction will be listed in 'BEST'
• If more more than one column shares the same highest result, they all get listed
• If all columns have the same result, they all get listed

Input:

I was reading this code (source):

I have prepare 2 tree view in separate iframe using jstree. The right tree view should control the left tree view. When user click one one the list in right tree view, the respective item folder will open and selected on left tree view. I can make it happen using div in single page. I control the left tree view using instance of left tree view in right jstree div var instance = $('#left').jstree(true);.

TL;DR: Why do I name go projects with a website in the path, and where do I initialize git within that path? ELI5, please.

I'm having a hard time understanding the fundamental purpose and use of the file/folder/repo structure and convention of projects/apps in the go language. I've seen a few posts, but they don't answer my overarching question of use/function and I just don't get it. Need ELI5 I guess.

Why are so many project's paths written as:

I'm new to Python. I have a dictionary where some fields are dates ( datetime.datetime type) and I need to use comprehension to convert those to MM/DD/YYYY strings in a new cloned dictionary.

I was getting started with

I'm using collapse list unstyled class for showing submenus.In that sub sub menus are not showing, only first submenu is displaying but not the second one.

I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc meta-method, but how to implement the increasing side?

Is it proper&enough to just increase refcount every time before adding the object to Lua stack?

Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc meta-method? This seems ugly as if something wrong with the Lua execution and the __gc is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.

In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT section of XS Map, and decrease refcount at destroyer.
