Dates not importing to SQL database correctly from Python

I have the following (subset of a) Pandas dataframe that I am trying to upload to a MySQL database: enter image description here

Here are details of the data using the info() function:

enter image description here

For added context, I previously converted both the tourn_date and date column to a datetime format using this code:

pd.to_datetime(all_data['tourn_date']).dt.date

Finally, here is the code that I'm using to import the data into the MySQL database:

for index, row in all_data.iterrows():
    inserts = [row.tourn_id, row.year, row.round_num, row.tourn_date, row.date]

    cursor.execute("""INSERT INTO AllPlayerStats 
                    (TourneyID, Year, RoundNum, TourneyDate, TDate)
                    values(%s,%s,%s,%s,%s)""", inserts)
db.commit()
cursor.close()

However, when I run this, some of the dates (like the ones shown above), are appearing as NULL in the database (see below) despite other tournaments working just fine and the format of the TourneyDate and Date columns in the database being of date type. In some instances, the tourn_date uploads correctly but the date doesn't.

enter image description here

Is there a way to troubleshoot this and understand why this is occurring? I'm very confused as to what's going on here.

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
