Recently, I was analyzing US housing price data and needed to normalize the values between 0 and 1 to make my model more effective. The issue was that the raw data had vastly different scales, and prices ranged

To manipulate a 3x3 array with random values in NumPy, you can start by generating the array using numpy.random.rand. To normalize each row, calculate the mean of each row using numpy.mean with the axis parameter set to 1. Then, reshape the row means to align with the array's dimension...
