How to Generate Sequences in Python

We can generate sequences in Python using the range function but it supports integers only. Of course, we can generate a series of integers and then to divide them elements by a number, like 10, but let’s discuss some more straightforward ways using numpy.

arange

We can generate a series using the numpy arange as follows:

import numpy as np

# start point = 0 , end point (not incl) is 1.05 and step is 0.05
np.arange(0, 1.05, 0.05)

And we get:

array([0.  , 0.05, 0.1 , 0.15, 0.2 , 0.25, 0.3 , 0.35, 0.4 , 0.45, 0.5 ,
       0.55, 0.6 , 0.65, 0.7 , 0.75, 0.8 , 0.85, 0.9 , 0.95, 1.  ])

linspace

With numpy linspace we can specify the starting point, the ending point and the number of points to be returned and then it estimates the steps.

np.linspace(0,1, 21)

array([0.  , 0.05, 0.1 , 0.15, 0.2 , 0.25, 0.3 , 0.35, 0.4 , 0.45, 0.5 ,
       0.55, 0.6 , 0.65, 0.7 , 0.75, 0.8 , 0.85, 0.9 , 0.95, 1.  ])
