It will reuse an instance container.register(FooService).depends(Bar).depends(Baz, option="Hello World!").shared() # without shared, a new instance will be created each time container.register(DogService).depends(Lucy) # could also container() obj = container.FooService() obj.action1() obj.action2() print('+-------------+') # could also container() obj2 = container.FooService() obj2.action1() print('+-------------+') obj3 = container.FooService() obj3.action1()Product's homepage
