Is it possible to create a variable number of placeholders?

When you create an init in a python class, you have a variable number or variables that you define.
Something like:

class Person:
   def __init__(self, arg1, arg2 ...):
       ...

And for each one you usually have:

self.arg1 = arg1
self.arg2 = arg2

Can I make a snippet in a way that for each arg I increase it generates a new self.argx = x?

Sorry. vsnip does not support dynamic snippet. You can use LuaSnip or UltiSnips for it.

No one else ever requested it as a feature? Because I really would like to use that feature instead of migrating to another snippet. If it's not the intention of the project at all to make that a feature, I'll use another project then.

Yes. dynamic tab-stop isn't a goal of this project.
The dynamic variable can achieve this (maybe) but it's too hard to implement. So for now, you should use other plugins for what you want, I think.
