Use a multidimensional index on a MultiIndex pandas dataframe?
I have a multiindex pandas dataframe that looks like this (called p_z): I want to be able to select certain rows based on another dataframe (or numpy array) which is multidimensional. It would look like this as a pandas dataframe (called tofpid): I also have it as an awkward array, where it’s a (26692, ) array (each of the entries
Is there a way to extract the current frame from a plotly figure?
Basically, I have a plotly animation which uses a slider and pause/play buttons to go through a dataset. I want to extract the number of the current frame (i.e., the current index in the ‘steps’/‘frames’ lists which the slider is on) in a Dash callback, so that I can update a table based on the main graph. For example, in
How to properly cluster with HDBSCAN for 1D dataset?
My dataset below shows product sales per price (link to download dataset csv): What I want to achive is clustering the dense regions (rectangles below) using HDBSCAN and sklearn. We have four regions, but regions 3 and 4 could also be grouped into a big region, which would lead to only 3 regions on the entire dataset by changing the
Recursing python dictionaries with yield from to generate list of nested dictionary keys
I want to generate a list of unique nested keys for each value in a dictionary such that: I thought something along these lines would work, appending each key to a list and recursing until a value is reached. At which point I yield a list and carry on. However when running, the result is all the unique keys Think

What I’ve got What I want: What i want Tried ax.annotation but it doesn’t work. Any suggestions? Preferencially, a for loop to annotate N points, considering the (x1, y1, z1) and (x2, y2, z2) coordinates.
Appending new value to the dataframe
Above code prints same value twice i.e. Why is it not appending NSEI at the end of the stocksList dataframe? Full code: Answer how your code is flawed Relying on the length of the index on a dataframe with a reworked index is not reliable. Here is a simple example demonstrating how it can fail. input: Pre-processing: Attempt to append
