Sorry, kind of a beginner question about BeatifulSoup, but I can't find the answer.

I'm having trouble figuring out how to scrape HTML tags without attributes.

Here's the section of code.

I am making a music key theory test.

In order to achieve something else that I won't explain right now here (maybe I will later though if this doesn't work), I need to take the root chord out of the list, store it somewhere else, and call back upon it for the user input when they are asked what key the chords come from.

I don't know how to do this, but I am pretty sure it is possible. I would love it if someone could help me. After I have this problem sorted out I will be much further.

Before, I was trying to find someway to have the actual variable represent the variable, while representing what the variable contains. So then after printing the randomized chords from the variable, the user can input the key from which the chords come from, which I have as the variable. But I don't think that will work.

I have an idea to make an application/program to help with music theory. It would spit out random chords of a certain key, and then you have to type in which key they come from. It would be an amazing tool for me, or anyone that wants to improve their knowledge of keys.

I am really far away from my goal, but right now I have this problem I need to get through.

I figured out how to make it spit out random chords from the key, but when I put the random.sample inside the while loop, it spits out the same 4 chords out of the 8 chords in the key each time it loops.

In order to make this application, I have this plan: Out of all the keys, choose a random one, A few random chords from that key are spit out, Then you figure out which key the chords come from, and you get another question (it repeats with another random key)

I am a beginner, and thought to make this it would include the while loop, but when it loops it spits out the same few random chords, just in different order.

P.S. I haven't figured out how to make it choose a random key yet. Maybe that would solve the problem I. D. K.

I've already tried using time.sleep(3) to make the while loop wait a bit before looping. I've already tried using other things than random.sample, but they just brought up more problems like only shooting out one chords (when i used random.choice(s)).

I want to calculate the entropy values for the multiple time series with the rolling window size of 500. I used roll-apply function with my code, but it is not working.

Please help me to calculate entropy (i.e. with the below code) in the rolling window size of 500.

For your convenience, here I am providing my entropy code so that it can be easier for you to suggest the application of rolling window size of 500 in the entropy method.

Approximate entropy was introduced to quantify the the amount of regularity and the unpredictability of fluctuations in a time series.

The function

Problem: My macro doesn't do what I want. I have an excel file with multiple columns. What I want is the macro

1. to look for specific headers (if they exist in the file), then
2. selects the entire column and
3. resize it as specified in the script. If the specified header doesn't exist in the file, the code should move on the next one without giving any error.

The code below changes the "Problem Description" size from 50 to 6 although 6 is the size for "Corrective Action Required?" header (which is not applicable in this case as that header doesn’t exist and hence the resizing requirement of 6 s/b simply ignored).

But that didn’t happened. Instead, the size of previous condition (changing the column size of "Problem Description" to 50 ) did change to 6.

Should I use a different method to write this macro and avoid using OnErrorResumeNext?
