I am trying to convert a input sentence Review into a CountVectorizer. I am struggling to handle the sentences that are passed through. How do I deal with the sentences and add vectors to these? Any assistance will be highly appreciated.

Input Data:

I am trying to run sentences through the Porter Stemmer algorithm, however am getting and error: AttributeError: 'list' object has no attribute 'lower'. can anyone assist, as I am not able to identify the problem:

Here is my input:

To add e.g. a click listener to a button there are (to my knowledge) two ways in Vaadin:

I'm stuck on my homework assignement.

I made a guessing game in Python, everything works like it should be except 1 thing.

I have added a lottie hamburger menu for a responsive one page site for the mobile break point. I would like two things happen as follows:

When clicked on one of the links the menu disappears.

at the same time the lottie animation goes back to hamburger icon state when clicked on a link, (it staying in X state) Here is the link https://codepen.io/OralYildiz/pen/abwvazw

I have been trying to avoid the use of for-loops in R in order to speed up calculations and simplify, relying on vector functions instead where possible. I've succeeded so far, until running into certain amortization calculations. I hit a brick wall and had to resort to a for-loop, see MWE code below. It works, ties out fine, but I'd like to replace it with vector or other more efficient functions. Can someone please help me replace the below with vector functions?

In the full code from which this MWE is extracted, it is reactive using Shiny. The periods and vector rates, actually all variables, change drastically depending on user inputs. The MWE example inputs variables are simplified.

In any case, the below is a very awkward, chainsaw approach and needs to be slimmed down. But I don't know how, having approached this from a complete XLS mindset where I have the most experience. If a for-loop is the only viable option for these sorts of calculations, I welcome any suggestions for improving the below MWE.

At the very bottom is code for a flawed attempt to "vectorize" but results are inaccurate when the vector variables change over periods. I show one of the problems with this vectorized approach in the image at the bottom where ending/beginning balances don't match when moving from one period to the next (the for-loop MWE code doesn't have those problems - it's functional but super clumsy).

For-loop MWE code:

The UI consists of a menu, a list view and a status bar. My goal is to make it responsive and resize properly.

The following line of code: MoveWindow(GetDlgItem(hWnd, IDC_LIST1), 0, 0, width, height, TRUE); basically takes the whole space, even the one provided for the status bar and whenever you resize the window, the ListView takes the entire space of the application. How can I make the ListView resizing respect the status bar?

I am using the default jetstream registration page in laravel 8:

I'm using dialog box-based Win API C++ GUI. Just read the docs and there is CreateStatusWindow API which is used to create the status bar, but I don't know how it can be fit into mine, because I'm using CreateDialogW.

CreateStatusWindow is obsolete, CreateWindow is recommended.

Note This function is obsolete. Use CreateWindow instead
