I'd like my Discord.py bot to display a random embedded message from a single channel

I have a discord channel that is full of embedded messages. I would like have the bot display a random embedded message from this channel in to any other channel where the command is called, similar to the functionality shown below.

When I call this code while pointed at the embed channel it returns an error: "discord.errors.HTTPException: 400 Bad Request (error code: 50006): Cannot send an empty message"

I believe this is caused by the channel being totally embeds, but I am very stupid and open to being corrected. I have confirmed that the bot has full admin privileges and thus can see/write into any channel. I've also confirmed that the below code works on non-embeds in other channels.

Thank you in advance for any assistance you can provide.

@client.command()
async def bestpost(ctx):
        channel = client.get_channel(channelID)
        best_posts = []

        async for message in channel.history(limit=500):
                best_posts.append(message)
        random_bestpost = random.choice(best_posts).content

        await ctx.send(random_bestpost)

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
