numpy.arange() method

How it works ?

Returns an array with evenly spaced elements as per the interval.

The interval mentioned is half opened i.e. [Start, Stop).

Length of array being generated = Ceil((Stop - Start) / Step)

Parameters : arange(start, stop, step, dtype)

• start : [optional] start range of interval . By default start = 0
• stop : end range of interval.
• step : [optional] step size of interval. By default step size = 1
• dtype : type of output array[can be int, flaot, complex]

Code :

# Working of 
# numpy.arange method
 
import numpy as geek
 
# reshape(2, 2) means 2D matrix of size 2 X 2 
print("Array 1 : \n", geek.arange(4).reshape(2, 2), "\n")
 
print("Array 2 : ", geek.arange(4, 10), "\n")
 
print("Array 3 : ", geek.arange(4, 20, 3))

Output :

Array 1 : 
 [[0 1]
 [2 3]] 

Array 2 :  [4 5 6 7 8 9] 

Array 3 :  [ 4  7 10 13 16 19]
