Simple python validation library which reports all validation errors instead of first failed?

I have tried voluptuous and schema, both of which are simple and great in validation, but they both do exception-based error reporting, i.e. they fail on first error. Is there a way I can get all validation errors of data in Voluptuous or Schema?

I found jsonschema that seems matching some of the requirements, but does not have validation for object keys, and custom function based validation (e.g. lambdas).

Requirement:

def myMethod(input_dict):

   #input_dict should abide to this schema -> 
   # { 'id' : INT , 'name':'string 5-10 chars','hobbies': LIST OF STRINGS }
   # for incorrect input like
   # {'id': 'hello','name':'Dhruv','hobbies':[1,2,3] }
   # I should be able to return all errors like
   # ['id' is not integer,'hobbies' is not list of strings ]
