Here is what the above code is Doing:
1. We create a new column for each bin.
2. We then populate the new columns with a 1 if the value in the original column is in the bin, and 0 otherwise.
3. We then drop the original column.
# dense to sparse from numpy import array from scipy.sparse import csr_matrix # create dense matrix A = array([[1, 0, 0, 1, 0, 0], [0, 0, 2, 0, 0, 1], [0, 0, 0, 2, 0, 0]]) print(A) # convert to sparse matrix (CSR method) S = csr_matrix(A) print(S) # reconstruct dense matrix B = S.todense()…
sklearn.metrics.pairwise.euclidean_distances(X, Y=None, *, Y_norm_squared=None, squared=False, X_norm_squared=None) Here is what the above code is Doing: 1. It’s calculating the euclidean distance between each row of X and each row of Y. 2. It’s returning a matrix of shape (n_samples_X, n_samples_Y) 3. It’s using the squared euclidean distance.
thread.interrupt_main() Here is what the above code is Doing: 1. It’s creating a thread that will run the function run_forever(). 2. It’s starting the thread. 3. It’s waiting for the thread to complete. 4. It’s interrupting the main thread. The output of the above code is: Thread started Thread interrupted Main thread interrupted As you…
with open(‘file_name.txt’, ‘a’) as f: f.write(file + ‘\n’) Here is what the above code is Doing: 1. Opening the file in append mode. 2. Writing the file name to the file. 3. Closing the file. The above code is fine, but it’s not very Pythonic. A more Pythonic way to write the above code is…

We are importing the random module. 2. We are importing the string module. 3. We are…
from tkinter import Tk from tkinter.filedialog import askopenfilename Tk().withdraw() # Added so Tk window doesn’t appear on opening the dialog filePath = askopenfilename() # Full pile will be returned as string Here is what the above code is Doing: 1. Create a Tk object. 2. Hide the Tk window. 3. Ask the user to select…
