I would like to extract the first observations of different groups from a dataframe. The number of observations comes from another dataframe.

Here is an example: In dataframe "x" there are different groups of animals with their names.

I have a package Foo installed as develop (] develop /path/to/Foo) which I use in my Julia scripts and Pluto notebooks.

Each experiment begins with

I am working with a pandas dataframe with multi-index columns (two levels). I need to drop a column from level 0 and later get a list of the remaining columns in level=0. Strangely, the dropping part works fine, but somehow the dropped column shows back up if you call df.columns.levels[0].

Here's a MRE. When I call df.columns the result is this:

MultiIndex([('Week2', 'Hours'), ('Week2', 'Sales')], )

Which sure looks like Week1 is gone. But if I call df.columns.levels[0].tolist()...

['Week1', 'Week2']

Here's the full code:

I have a webapi that returns some Json:

This might be connected to this or this. However, none of the suggested solutions works for me.

I'm using VSCode with the Julia extension and I run everything in a Jupyter notebook. My first cell looks as follows.

I have my own Julia package called foo which is stored in /private/tmp/foo and looks like:

This is my first stack overflow question, so if I am presenting something wrong, please let me know. I am pretty new to computer programming, so I just have a small webpage where I am just implementing things that I am learning.

I made a little quiz with random trivia multiple choice questions you can take if you press a button. I am using window prompts to ask the questions and get the answers, and I have all of the questions and answers stored as objects with question/prompt and answer pairs. All of those objects are stored in an array in a variable called shortQuizPrompts. I already have the quiz working and everything, aka., It tells you after every question if you got the answer to that question right or wrong, and it gives you a grade afterwards... I also have it set up so that if you enter an answer that is not "a", "b", "c", or "d", it lets you know that it isnt a valid answer. Those sorts of things.

As of right now, you can choose how many questions long you want the quiz to be out of the 24 total questions I have so far. It just asks the questions in the order that they are stored in the array. For example, you will never be asked the last question in the array if you do not choose for the quiz to be the full 24 questions long. However, I want to make the quiz ask the questions in a random order, while also removing those questions from the array as to not ask the same question multiple times.

I have tried increasing the iterator while looping through the array to a random number from 0 to the length of however many questions they chose. Then checking to see if the iterator was larger than the length of the number of questions they chose, it would decrease the iterator until it found a question that is still in the array that it could ask...

If anyone knows how to go about doing that, it would be great. Sorry for the long question btw. I am pretty new to coding, so this is probably a simple answer, but I digress. I'm pretty sure I did everything right. Thx.

I am doing this for a lab at school, however, in my code i get the correct outputs, but for some reason my inputs are repeating themselves. I am unsure why they are doing this, and have tried editing my code in several different ways in order to fix the problem, but to no avail.

here is my original code:

I have recently started using Pluto.jl, and it is quite nice (and visually appealing). The question is: how do I set up a "pluto server", like the similar thing with jupyter. It must be easy, but I see no docs.
