npfromfile

numpy.fromfile is a function in the NumPy library that reads binary data from a file and stores it in a NumPy array. The function takes the filename and the data type of the elements in the file as arguments. If the data type is not specified, NumPy tries to guess the data type based on the file format. The function returns a NumPy array that contains the data read from the file. The fromfile function is useful for reading large datasets that are stored in binary format.
