Is it possible to initialize class variables in the dictionary. Python3.8

Is it possible to somehow assign the values ​​of the class transferred to each variable in the dictionary. For example, the class has variables: a, b, c, d -, and I convey the dictionary to the designer of the class:

  Dictionary = { `` ""> 'b' :  5 ,  'a' :  2 ,  'c' :  45 }     
 the designer should contact the variable class by the names of the keys to the dictionary and set these values ​​to them, while the keys can be arbitrary. DATA-HIGHLIGHTED = "">  class   expain :   def   __ Init __  ( self, d:  dict  ):  self.a, self.b, self.c =  int   # there should be a code to initiate variables transferred to dictionary    if  __name__ ==  '' __ main __ ':  dictionary = {' 'b'   5 ,  'a' :  2 ,  'c' :  45 }  ex = Example (dictionary)   print  (ex.b) # must deduce: "5" ".
