The above example creates a NumPy array containing NaN values and prints a boolean array indicating which elements in the original array are NaN values. nums = np.array(...): Here np.array(...) creates a 2D NumPy array named 'nums' with 3 rows and 4 columns. Some of the elements in...
When usingpandas, we usevalue_counts()function which returns a Series containing counts of unique values in descending order. By default, it excludes NA/null values. If your sequence contains missing values (NaN), we should handle them appropriately based on the requirements. For example, we ca...
