numpy arange code example

Example 1: np arange

np.arange([start], stop, [step])

>>> np.arange(10) # stop
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> np.arange(2, 10)
array([2, 3, 4, 5, 6, 7, 8, 9])
>>> np.arange(2, 10, 2)
array([2, 4, 6, 8])

Example 2: np.arange in python

>>> np.arange(3)
array([0, 1, 2])
>>> np.arange(3.0)
array([ 0.,  1.,  2.])
>>> np.arange(3,7)
array([3, 4, 5, 6])
>>> np.arange(3,7,2)
array([3, 5])

Example 3: numpy arange

arange() NumPy arange() is one of the array creation routines based on numerical
ranges.
It creates an instance of ndarray with evenly spaced values and returns the 
reference to it.

Example 4: numpy arange number of elements

>>> import numpy as np
>>> np.linspace(start=0, stop=7.5, num=4)
array([ 0. ,  2.5,  5. ,  7.5])
>>> list(_)
[0.0, 2.5, 5.0, 7.5]
