Python create objects in for loop

Question

I have a class to assign some parameters:

class body:
 def __init__(self, name, number, L):
 self.name = name
 self.number = number
 self.L = L

And I would like to assign these parameters to 10 almost equal bodies like:

for i in range(0, 10):
 body[i].name = "test_name"
 body[i].number = i
 body[i].L = 1.

And to be able to change, lets say, the parameter L of body 3 from 1 to 2:

body[3].L = 2

Thank you very much for the help.

Answer 1

Note that body is a class. Using body[i] suggests you may be intending to use body as a list. If you want to create a list of 10 instances of body, do not name the list body as well. You could instead name the list bodies and define it with a list comprehension:

bodies = [body("test_name", i, 1.) for i in range(0, 10)]
bodies[3].L = 2

By the way, PEP8 Style Guide recommends all classes follow the CapWords convention. So to conform with the convention, body should be Body. By following this convention, everyone reading your code will understand immediately what is a class and what is not.
