I have been trying to replace part of the texts in a Pandas dataframe column with keys from a dictionary based on multiple values; though I have achieved the desired result, the process or loop is very very slow in large dataset. I would appreciate it if someone could advise me of a more 'Pythonic' way or more efficient way of achieving the result. Pls see below example:

I got a button (using MaterialDesign theme) in a WPF form button that is not styling correctly, where am I going wrong?. The button in the DataGrid is fine. I tried near Window on mainWindow doing Foreground="white" but when I take the theme off everything returns to nornal WPF form with the text colour (lower right) missing

How can i get selected checkbox of the datatable by inputing numbers

I'm trying to code a bootstrap data table which able to select check box of the rows by inserting no of rows in the input box

I am trying to iterate over a dictionary (inside another dictionary specifically, but I don't think that part matters), and I'm unable to get the for loop to iterate over the values in the order that they were placed in. I would like to be able to take the first value of each dictionary. I thought that after python 3.6, dictionaries kept their order (here), but these wont stay in order.

This is what my dictionary looks like:

Problem: The problem is when i create multiple note at a time like i create 3 notes in same time and i wrote same text in first note and save it, the remaining empty note will not be remove when it reload or refresh the page. So how can i achieve this when the notes is empty, it should be remove and it should not be saved in local storage only those noes will be saved when one is not empty. You can run this code on your local machine to see output.

It is a fairly short and straight forward code. It waits for a submit and alerts "success" if it happens. But nothing is happening and no error is showing. I have tried doing minor variations and using an arrow function, but nothing seems to work. I am fairly new to Java and a lot of the codes I write have bugs but this code seems too simple to have a bug.
