Convert pandas selected columns into a 2D numpy array

Question

I have a pandas dataframe with 10 columns and N rows. I want to select two columns from my data frame and put them into a NumPy 2D array with dimensions (N, 2). How to do that?

Answer 1

There is a way to convert a dataframe to a numpy array: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_numpy.html

You could just select the columns you want:

df[['Col1','Col2']].to_numpy()
