QUESTION
I have a dataset with the name of Danish ministers and their position from 1990 to 2020 (data comes from dataset called WhoGovern; https://politicscentre.nuffield.ox.ac.uk/whogov-dataset/). The dataset consists of the ministers name, the ministers position, the prestige of that position, and the year in which the minister had that given position.
My problem is that some ministers are counted twice in the same year (i.e., the rows aren't unique in terms of name and year). See the example in the picture below, where "Bertel Haarder" was both Minister of Health and Minister of Interior Affairs in 2010 and 2021.
I want to create a dataset, where all the rows are unique combinations of name and year. However, I do not want to remove any information from the dataset. Instead, I want to use the information in the prestige column to combine the duplicated rows into one. The observations with the highest prestige should be the main observations, where the other information should be added in a new column, e.g., position2 and prestige2. In the example with Bertel Haarder the data should look like this:
(PS: Sorry for bad presenting of the tables, but didn't know how to create a nice looking table...)
Here's the dataset for creating a reproducible example with observations from 2010-2020:

So I am relatively new to programming, and I have been working on this task app, where I want to save the data such as task name and more, given by the user. I am trying to accomplish this using Room. Now, initially, when I tried to do it, the app would crash since I was doing everything on the main thread probably. So, after a little research, I came to AsyncTask, but that is outdated. Now finally I have come across the Executer. I created a class for it, but I am a little unsure as to how I can implement it in my app. This is what I did :

QUESTION
FlatButton is deprecated and shouldn't be used. Used TextButton instead.
On my previous FlatButton widget, i was able to changed the splash color when on pressed. But now I'm using TextButton widget, how can i changed its color the efficient way on the MaterialApp ThemeData or directly on the TextButton widget.
Currenly this is my TextButton
...ANSWER
Answered 2021-Apr-06 at 08:40First keep in mind that the primary property on a TextButton sets the colour of its text and icon. It does not change the ripple color. Secondly in Textbutton there is no direct property to change splash color. So if you want to change splash color to transparent you can do it like this.

QUESTION
I'm curious to see if anyone has any thoughts on how to accomplish this in Python with Pandas.
I have a dataframe (df1) with the credit card transaction details that contains the Point of Sale description (df1['Description']) and amount (df1['amount']). The POS description is unique to each location so you end up with several descriptions for Amazon, Shell Oil, etc.
I have another dataframe (df_lookup) that will serve as a lookup table to classify the transactions. This dataframe will include the name (df_lookup['Name']) and the category to classify each transaction df_lookup['Category']).
This is what I would like to accomplish: Compare the df1['Description'] to df_lookup['Name']. If the df1['Description'] contains the df_lookup['Name'], the corresponding df_lookup['Category'] will be added to df1 as a new column df1['Category']. Please see the examples of each dataframe and the desired outcome below.
Example of df1:
Description Amount AMAZON.COM*ajlja09ja AMZN.COM 10 AMZN Mktp US *ajlkadf 15 AMZN Prime *an9adjah 20 Shell Oil 4106541031 20 Shell Oil 4163046510 25Example of df_lookup:

QUESTION
I am reading the book Object Oriented Programming in Common Lisp from Sonja Keene.
In chapter 2, the author says:
The procedure for determining which methods to call and then calling them is called generic dispatch. It happens automatically whenever a generic function is called.
This reminds me of the Dynamic Dispatch definition which is (according to Wikipedia):
Dynamic dispatch is the process of selecting which implementation of a polymorphic operation to call at run time. It is commonly employed in, and considered a prime characteristic of, object-oriented programming languages and systems.
Unfortunately, the wikipedia does not have an entry about generic dispatch.
Thus, I would like ask:
1 - Are dynamic dispatch and generic dispatch basically the same thing? What are the similarities?
2 - And what are the differences? Is dynamic dispatch some sort of subset of generic dispatch due to the flexibility of CLOS?
...ANSWER
Answered 2021-Jun-09 at 06:32Yes, dispatch in CLOS is also dynamic (this is also called late binding).
No, dynamic and generic dispatch are not the same thing, because the words generic and dynamic answer different questions.
The point that the word dynamic makes is that the decision about which method(s) to call is made at run time. The contrast to that would be static dispatch (which some would not call dispatch but overloading), where the decision is made at compile time.
The point that the word generic makes is that the decision about which method(s) to call is made on the basis of the type of all (required) arguments. The methods are attached to the generic function. The contrast to that would be class based dispatch, where the decision is made only on the class of the first argument and the methods are attached to that class.
