Regex : split on '.' but not in substrings like "J.K. Rowling"

I am looking for names of books and authors in a bunch of texts, like:

my_text = """
    My favorites books of all time are:
    Harry potter by J. K. Rowling, Dune (first book) by Frank Herbert;
    and Le Petit Prince by Antoine de Saint Exupery (I read it many times). That's it by the way.
"""

Right now I am using the following code to split the text on separators like this:

pattern = r" *(.+) by ((?: ?\w+)+)"

matches = re.findall(pattern, my_text)

res = []
for match in matches:
    res.append((match[0], match[1]))

print(res) # [('Harry potter', 'J'), ('K. Rowling, Dune (first book)', 'Frank Herbert'), ('and Le Petit Prince', 'Antoine de Saint Exupery '), ("I read it many times). That's it", 'the way')]

Even if there are false positive (like 'that's it by the way') my main problem is with authors that are cut when written as initials, which is pretty common.

I can't figure out how to allow initials like "J. K. Rowling" (or the same without space before / after dot like "J.K.Rowling")

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
