Is it possible to increment the value of a range of array elements by a constant without looping through the list?

Question

Are there any modules or libraries in python that could help me with this? I mean to do this with a complexity of O(1).

Answer 1

You can use numpy to do this

>>> import numpy as np
>>> data = np.arange(10)
>>> data
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> data[2:6] += 5
>>> data
array([ 0,  1,  7,  8,  9, 10,  6,  7,  8,  9])
