Public

• by default all variables, method and class are considered as public access for python

Private

• python don't have any specific syntax or modifier name to specify if object is private or not
• python has convention to specify private variables, you can still access that variable if you really want to
• in python you need to add double underscore as prefix to specify if object is private or not
• To access private variable you need to add _ClassName as prefix with variable name

  class MyClass:
      def __init__(self, value):
          self.__value = value
  
  c = MyClass(10)
  print(c._MyClass__value)
  

  10
  

Protected

• same as private variable only difference is that we only need to use single underscor _ as prefix
• also you can directly access protected variable in python, unlike private
• so in above code c._name will print protected variable
