Stars are fundamental pieces that compose our Universe. By studying them we can better comprehend the environment in which we live. In this work, we have studied a sample of 350 nearby O and B stars and have characterized them in aspects of their multiplicity, temperature, spectral classifications, and projected rotational velocity.

Python is a robust language with a steep learning curve, i.e. one can make rapid progress with it. In this proceeding, we will present how we used Python in our research.
