Using frombuffer will also result in a read-only array if the input to buffer is a string, as strings are immutable in python. frombuffer(buffer, dtype = float, count In this tutorial, we will learn about the difference between frombuffer () and fromstring () in Python NumPy with the help of examples. Parameters bufferbuffer_like An object that Introduction NumPy frombuffer () function is used to create a numpy array from a specified buffer. The buffer represents an object that exposes a buffer interface. frombuffer() function of the Numpy library is used to create an array by using the numpy.
