Filter pandas dataframe by multiple columns, using tuple from list of tuples

So I have been referencing this previous question posted here Filter pandas dataframe from tuples.

But the problem I am trying to solve is slightly different.

I have a list of tuples. Each tuple represents a different set of filters I would like to apply to a dataframe accross multiple columns, so I can isolate the records to perform additional tasks.

Whenever I try and filter by a single tuple within the list of tuples, the dataframe I get back has no records.. If I break the tuple values out in a very long form way it works fine. Not sure what I am missing or not thinking about here..

Using the same example from the post I have been referencing....

AB_col = [(0,230), (10,215), (15, 200), (20, 185), (40, 177), 
                (0,237), (10,222), (15, 207), (20, 192), (40, 184)]

sales = [{'account': 'Jones LLC', 'A': 0, 'B': 230, 'C': 140},
         {'account': 'Alpha Co',  'A': 20, 'B': 192, 'C': 215},
         {'account': 'Blue Inc',  'A': 50,  'B': 90,  'C': 95 }]
df = pd.DataFrame(sales)

example dataframe

The answer from the other question

df = df[df[["A","B"]].apply(tuple, 1).isin(AB_col)]

Which returns

example results

However, I want to only get one record back, that matches the first tuple in the list of tuples. So I tried this

df[df[["A"]].apply(tuple,1).isin(AB_col[0])]

But get no records returned

my modification results

However, I can do this which gets me the results I want, but when I have essentially a list of tuples that is every combination of column values to use a filters for different levels of calculations, this seems like way too much code to have to use to product the desired results

df[(df['A']==AB_col[0][0]) & (df['B']==AB_col[0][1])]

Which gets me results I want

long form results but what i need

Is there a way to get to this same result more efficiently?

Thanks!

How to split a rinex file if I need 24 hours data

Trying to divide rinex file using the command gfzrnx but getting this error. While doing that getting this error msg 'gfzrnx' is not recognized as an internal or external command Trying to split rinex file using the command gfzrnx. also install'gfzrnx'. my doubt is I need to run this program in 'gfzrnx' or in 'cmdprompt'. I am expecting a rinex file with 24 hrs or 1 day data.I Have 48 hrs data in RINEX format. Please help me to solve this issue. source https://stackoverflow.com/questions/75385367/how-to-split-a-rinex-file-if-i-need-24-hours-data

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
