python - Determinate if class has user defined __init__ -


i'm trying identify if class received via argument has user defined __init__ function in class passed. not in super class.

class hasinit(object):   def __init__(self):     pass  class noinit(object):   pass  class base(object):   def __init__(self):     pass  class stillnoinit(base):   pass  def has_user_defined_init_in(clazz):   return true if # magic  assert has_user_defined_init_in(hasinit) == true assert has_user_defined_init_in(noinit) == false assert has_user_defined_init_in(stillnoinit) == false

i think work:

def has_user_defined_init_in(clazz):     return "__init__" in clazz.__dict__

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
