In Pandas, you can replace NaN (Not-a-Number) values in a DataFrame with None (Python's None type) or np.nan (NumPy's NaN) values. Here's how you can replace NaN values with None: import pandas as pd import numpy as np # Create a sample DataFrame with NaN values data = {'A'...
To replace NaN's in NumPy array with closest non-NaN value, you need to create/define a mask for checking NaN values and filter all the indices of NaN values using the defined mask. And then, linearly interpolate these values, and it will fill the nearest numerical (non-NaN) value. The...
