To use np.argsort in descending order in Python, first apply np.argsort to our array, and then either invert the result using array slicing ([::-1]) or negate the array before sorting. For inverting, sort the array using np.argsort and then reverse the resulting indices. For negating, ...
Following are some quick examples of how to use the log() function in Python NumPy. # Quick examples of numpy log() function # Example 1: Get the log value of scalar arr = np.array(2) arr1 = np.log(arr) # Example 2: Get the log values of a 1D array arr = np.array([1, ...
Use thenp.random.seed()function to set the seed for the random number generator. For instance, First, import the NumPy library and use the aliasnp. Set the seed to a specific value, in this case, 42. You can replace 42 with any integer. Generate a 3×3 array of random numbers from...

1. Alias for None: np.newaxis is equivalent to using None. For example, arr[:, np.newaxis] is the same as arr[:, None]. 2. Higher-Dimensional Arrays: It can be used multiple times in slicing to add multiple axes simultaneously....
