How to perform a draw in python following a certain distribution, such as Gaussian or Maxwell-Boltzmann distributions?

My problem is to draw velocity values for a hydrogen molecule according to a Maxwell-Boltzmann distribution that will collide with an electron (with well-defined energy) and will split into two fragments (2 hydrogen atoms). I wanted to have a notion of how to draw velocity values for my initial molecule according to the Maxwell-Boltzmann distribution, entering values of mass of the molecule, temperature and distance from where the collision occurred to the detector.

You want to use a continuous Maxwell random variable?

In the module documentation random has a specific section on distribution where the Gauss distribution is included. Take a look there, who knows help you.

The scipy module has the integrated Maxwell-Boltzmann distribution, the Random module only has the Gauss method. The scipy module is better and with greater statistical ability and will give you the easiest-to-use probability density function!
