How can I select k samples between two numbers from a Gaussian (normal) distribution in Python?

E.g. The samples should be between 10 and 12.

You can use Numpy's normal() function to draw samples from the parameterized normal distribution. You need to set the values of parameters "loc" [mean ("centre") of the distribution] and "scale" [standard deviation (spread or "width") of the distribution] properly to get the samples between a range.

Here is an example to select ten samples between 10 and 12 from a Gaussian distribution.

>>> import numpy as np
>>> rnd=np.random.default_rng()
>>> rnd.normal(loc=11, scale=0.1, size=10)
array([10.90239842, 10.98048705, 11.05175105, 10.96414277, 10.79745089, 10.95877718, 11.0053723 , 10.82757506, 10.97739127, 11.08950675])
