python - Extending list class to make a list of objects -

i have particle list of objects of type particle, takes 2 parameters, position , energy:

class particle(object):     def __init__(self, pos, energy):         self.x = pos         self.e = energy

the way i've managed far create list of particles using list comprehension:

number_of_particles = 10 initial_energy = 0 particle_list = [particle(initial_energy,i) in range(number_of_particles)]

which allows me things like:

particle_list[0].x

which want.

however, really, follows:

particle_list = particlelist(no_of_particles, initial_energy)

and create exact same list.

i assume have extend list class somehow i'm @ loss how this.

why not build function you. simple like:

def particlelist(no_of_particles, initial_energy):     return [particle(initial_energy,i) in range(number_of_particles)]

this should simple way of getting list.
