Singleton
[source]¶ Bases:
object
Implements the singleton pattern.
Example
Create a singleton class:
class MySingleton(Singleton): def __init__(self): super().__init__() self.value = 0 def add(self): self.value += 1
Use the singleton:
MySingleton.get_instance().add() MySingleton.get_instance().add() print(MySingleton.get_instance().value)
Ensures there is only one instance created. Make sure to use super() in subclasses.
