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...

Example-1: Use of zeros() function with one argument The following example shows the use of the zeros() function. 10 has given in the argument value of this function to create a one-dimensional NumPy array. The data type of the array will be printed. reshape() function is used to chan...
NumPy library has many functions to create the array in python. where() function is one of them. Some operations can be done at the time of array creation based on the condition by using this function. How to use python NumPy where() function with multip

This tutorial will explain how to use he Numpy full function in Python (AKA, np.full or numpy.full). Numpy full creates a Numpy array filled with the same value At a high level, the Numpy full function creates a Numpy array that’s filled with the same value. ...
Using Python numpy.where() Suppose we want to take only positive elements from a numpy array and set all negative elements to 0, let’s write the code usingnumpy.where(). 1. Replace Elements with numpy.where() We’ll use a 2 dimensional random array here, and only output the positive...
Notice that there are two input arguments to the function, which I’ve namedarr1andarr1. These should be Numpy arrays or array-like objects such as Python lists. Also, there are some restrictions on theshapeof the input array. One way to use np.multiply, is to have the two input arra...
