Is my for-loop that iterates through a list of strings and function correct? [closed]

I am trying to iterate through a data frame that has these columns as the names. Is this correct? For context, The lists above are the column names, and the newel_var is the new columns I am creating as a result. This is what I Have

#Difference between home and away variabls to also help visualize and create
#curvefit lines #must create columns in data frame that include these 

stats_by_yr.keys()

##lists holding the column names for each column based on home or away

home_var = [ "PTS_home","FG_PCT_home", 'FT_PCT_home',
                'FG3_PCT_home', 'AST_home', 'REB_home', "HOME_WIN_PCT" ]
away_var = [ "PTS_away","FG_PCT_away", 'FT_PCT_away',
                'FG3_PCT_away', 'AST_away', 'REB_away', "AWAY_WIN_PCT"]
newcol_var = ["PTS_dif","FG_PCT_dif", 'FT_PCT_dif',
                'FG3_PCT_dif', 'AST_dif', 'REB_dif', "WIN_PCT_dif"] #new columns i will integrate into my original dataset

for i in newcol_var:
    home = home_var[newcol_var.index(i)]
    away = away_var[newcol_var.index(i)]
    
    def dif(newcol, home, away):
        stats_by_yr[newcol] = stats_by_yr[home]-stats_by_yr[away]
        return 
    
    dif(i, home, away)
    
differences = stats_by_yr[newcol_var]
stats_by_yr["SEASON"] = range(2003,2022,1)
stats_by_yr

For reference, "stats_by_yr" is the data frame I am Using that contains the column names and observations under those names. It is a Pandas data frame. I Get the result I want that being 7 new columns containing the newcol_var and their respective values, but my code looked a bit wrong. Here is my cleaned data frame if anyone can hekp

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
