Maximum value of the above flattened array: 3 Minimum value of the above flattened array: 0 Explanation: In the above exercise – a = np.arange(4).reshape((2,2)): This line creates a 2D array of shape (2, 2) using the np.arange function and then reshape it to the desired shape ...
nums = np.array(...): Here np.array(...) creates a 2D NumPy array named 'nums' with 3 rows and 4 columns. Some of the elements in the array are NaN (Not a Number). print(np.isnan(nums)): Here np.isnan() function returns a boolean array of the same shape as 'nums', whe...
