Python Languauge Utilities

This library provides utilities to use features of other languages in Python.

This fork contains some improvements on top the the original repo.

Usage:

Access Modifiers:

• Identify a variable as private:

  from pythonlangutil.access_modifiers import private_variable
      
  class PrivateVariableTest(object):
      def __init__(self):
          self.id = "123"
          
      @private_variable('id')
      def __setattr__(self, *args, **kwargs):
          return object.__setattr__(self, *args, **kwargs)
      
      def insider(self):
          self.id = "321"

• Identify a method as private:

  from pythonlangutil.access_modifiers import private_function
  
  class PrivateFunctionTest(object):
    def __init__(self):
        pass
    
    @private_function
    def private_method(self):
        return 'called from inside my own class'
    
    def insider(self):
        return self.private_method()

Method Overloading:

   class OverloadTest():
       def __init__(self):
           self.male_pref = "Mr. %s"
           self.female_pref = "Ms. %s"
           self.general_pref = "Dear %s"
       
       @Overload
       @signature(str, bool)
       def my_method(self, name, male):
           if male:
               return self.male_pref % name 
           return self.female_pref % name
   
       @my_method.overload
       @signature(str)
       def my_method(self, name):
           return self.general_pref % name
       
       @my_method.overload
       @signature(int, str)
       def my_method(self, times, name):
           return "\n".join([self.general_pref % name for i in range(times)])

Singleton pattern:

It prevents the instantiation of the class. The only instance of the class will be accessible through get_instance() method which will be added to class automatically.

   from pythonlangutil.singleton import Singleton

   @Singleton()
   class SingletonTest():
       def __init__(self):
           pass
