I would like to create a new variable that is the dot product of two variables in a subgroup of my dataframe. I know that when I want to create a group-level variable, I can use the transform method. For example, in the dataset auto (download) I can average the price of the brands as follows:

I am trying to make a discord.py bot that plays a game. So far I have gotten it to make one file for the whole system, although I want different ones for each user. I have been using pickle and I haven't been seeing a way to do this anywhere. I have been having a hard time making stuff that is specific to a user so that's also a problem. If there isn't any way to do this let me know. Here is my code so far:

Here's my json

[{"year":"1980","Manufacturer":"Oldsmobile","Model":"Cutlass","Product":""},{"year":"1980","Manufacturer":"Oldsmobile","Model":"Sierra","Product":""},{"year":"1980","Manufacturer":"Toyota","Model":"4Runner","Product":""},{"year":"1980","Manufacturer":"Ford","Model":"Fiesta","Product":""},{"year":"1980","Manufacturer":"GMC","Model":"Terrain","Product":""}]

and my HTML

So I would like to make a plot that would have my points for 3 different groups (cars) but as a general area , much like the blobs on this sketch. Ideally it would have a darker hue in the areas where the points lay. Any ideas?

DATA TO WORK WITH

First question here! So, i'm at the beginning of my studies and i have searched on Google and didn't found anything about this scenario:

I'm developing a website that contains a lot of files (over 500 on the same page, it's a list of cards). If i write all the tags of those images the code will be a mess.

I would like to know if would be possible for example to create a ".txt" file with all the img tags inside it, and make a call through JavaScript or jQuery, so that they are displayed on the screen. For example:

I am testing how to change text and CSS elements using Javascript

I have three buttons in my HTML, only one so far that I am using (Change Title). I would like to change the H1 Text when I click the button.

Using my current coding, when I click the button nothing happens and I get the following displayed in the web developer tools console:

*ReferenceError: changeTitle is not defined [Learn More] Index.html:1:1

Onclick file:///D:/Google%20Drive/Programming/EDX/Introduction%20to%20JavaScript/Module_1/index.html:1:1*

Questions:

1. Can someone please help me understand why the browser says that the changeTitle function is not defined when I believe I have defined it in the external JS file.
2. Am I able to use the onclick method?? in the tag element so that I do not have to use buttons?

I have 2 issues.

1. When I try to split my data into test and train sets, using sample.split as below, the sampling is done rather unclearly. What I mean is that the data d, has a length of 392 and so, 4:1 division should show 0.8*392= 313.6 i.e. 313 or 314 rows in test set, but the shown length is 304. Is there something that I might be missing?

I have an rdd as rowsrdd given below, to which i have apply aggregation by using keyby() on keys (0,8) and reducebykey() on key (1):
