WebYou can use the numpy.arange () function to create a Numpy array of integers 1 to n. Use the following syntax – # create array of numbers 1 to n numpy.arange(1, n+1) The numpy.arange () function returns a Numpy array of evenly spaced values and takes three parameters – start, stop, and step. Webnumpy.repeat Repeat elements of an array. ndarray.resize resize an array in-place. Notes When the total size of the array does not change reshape should be used. In most other cases either indexing (to reduce the size) or padding (to increase the size) may be a more appropriate solution.
