Python: Quick and dirty datatypes (DTO)

Question

Very often, I find myself coding trivial datatypes like

class Pruefer:
    def __init__(self, ident, maxNum=float(\'inf\')         


        

Answer 1

An alternate approach which might help you to make your boiler plate code a little more generic is the iteration over the (local) variable dicts. This enables you to put your variables in a list and the processing of these in a loop. E.g:

class Pruefer:
     def __init__(self, ident, maxNum=float('inf'), name=""):
         for n in "ident maxNum name".split():
             v = locals()[n]  # extract value from local variables
             setattr(self, n, v)  # set member variable

     def printMemberVars(self):
         print("Member variables are:")
         for k,v in vars(self).items():
             print("  {}: '{}'".format(k, v))


P = Pruefer("Id", 100, "John")
P.printMemberVars()

gives:

Member Variables are:
  ident: 'Id'
  maxNum: '100'
  name: 'John'

From the viewpoint of efficient resource usage, this approach is of course suboptimal.
