QUESTION
I am using Wikipedia-API 0.5.4, and I would like to retrieve the item ID for the item being discussed on a given page. Is it possible to do this using the data returned from a page query?
I am able to retrieve the pageid. However, pages in different languages about the same item do not have the same pageid, but they do refer to a single item a unique item ID.
In the example below, the pageid for the English language page on the singer Cher is different from the pageid for the corresponding French language page, while the item ID for "Cher" should be the same in both cases.
Is the item ID not accessible from the page object?
...ANSWER
Answered 2021-Apr-15 at 16:35I ended up using the requests library to use the Wikipedia REST API directly. Including prop=pageprops will return the item ID, which is shared across different languages.

QUESTION
I hope you all having a great day.
Here is the deal, whenever I load a lot of products from API that has one image each one of the products, the app kind of does a restart, and it loads from the beginning.
In the beginning it was with simple tag, I changed it to ion-img, and I saw that there was a big difference using the ion-img tag because it lazy loads the images.
But still, when I have loaded more that 40-60 products, and those images are loaded, the app still refreshes.
I remove the images, no images are shown, and the app works fine, but the app needs those images.
What might be the issue here? Am I missing something?
Click Here for Streamable 1 video
Here the client wants to see product categories with a lot products in it
Click here for Streamable 2 video.
Here the client wants to select a product, but when it does, the app restarts.
The second video, is where I have tried, to remove the top 15 products, when get the next 15 on infinite scroll, but a scrolling flick happens because of that.

Chances are you need to use ion-virtual-scroll to handle the memory management. In particular, note the documentation regarding iOS and wkWebView.

const mapDispatchToProps = dispatch => {
return {
fetchSongs: () => dispatch(fetchSongs())
}
}
export default connect(mapStateToProps, mapDispatchToProps)(MainPage);
ANSWER
Answered 2020-Dec-02 at 14:30Object.keys(songsData.songs).map() is uncessary.
From the JSON, We can see that the array we want to iterate over is songsData.songs.toptracks.track.
Also, in the state, songs is initialised as an empty array. But event FETCH_SONG_SUCCESS changes songs to be an object. It should ideally be initialised as songs: {} in the initialState
And for initial render - where songs is still empty, it does not have property toptracks on it. So we have to make sure songsData.songs.toptracks is truthy before we actually access and iterate over songsData.songs.toptracks.track.
Here is the snippet that should do the job:
QUESTION
I am having issues eliminating the second item of the lists nested inside a list of dictionaries. I think it may be because there are a couple of empty lists, so the indexing does not work. How can I delete the second item of each nested list pair but also skip the empty lists?
In the end, the nested list should be flattened as it does not have a second pair anymore.
The list looks something like this:
