Is there a "shortcut" to declare a single object as in javascript? [duplicate]

Question

In javascript, we have this object declaration:

var object = {property1:1,property2:1 }

In python, the traditional way we do that:

class my_cls:
  def __init__(self):
    self.property1=1
    self.property2=1
object = my_cls()

is there a shortcut in python to declare an object?
