If you need to remove the duplicate columns from a 2D NumPy array, set theaxisargument to1when callingnumpy.unique(). main.py importnumpyasnp arr=np.array([[3,3,5,6,7],[1,1,4,5,6],[7,7,8,9,10]])print(arr)print('-'*50)unique_2d=np.unique(arr,axis=1)print(unique_2d) ...

fixes #1110 DropNullColumn (provisional name) takes as input a column, and drops it if all the values are nulls or nans. TableVectorizer was also updated with a drop_null_columns flag set to False ...
Without the dynamic array functions, life gets more complicated = IFERROR( INDEX( fails, SMALL( IF( COUNTIFS(fails, fails, k,"<="&k)=2, k ), k ) ), "" ) where 'k' is a unit based index column. † Aside: I've realised that it is so many years since I last...

Once again, we will be selecting a specific column of our dataset to apply the method. from scipy import stats z = stats.zscore(df_boston["DIS"]) z_abs = np.abs(z) The first line in the above code is just importing the library. The second line uses the scipy.zscore method to...
The sample dataset contains some non-printable characters in the Student Name column. We will try to remove these characters using the following methods. Method 1 – Use CLEAN Function to Remove Non-Printable Characters Click on any cell (D5). Enter the following formula: =CLEAN(C5) Click ...
Good Day, Friends!I have one column in sheet1 and the other in sheet2.Columns have duplicates, within itself as a column, as well as when both columns are...
