Consider the following Python shell session (Python 3.6.2, Win64):
>>> def givemetwo(): ... x = 'two' ... print(id(x)) ... >>> givemetwo() 1578505988392 So far fine. My understanding of object existence made me think that the object referred to by x would be deleted when the givemetwo() function returned, like a local variable in C. However, this isn't true, as shown by the following in the same session: >>> import ctypes >>> print (ctypes.cast(1578505988392, ctypes.py_object).value) two This shows that the object still exists, which was a surprise. Will this object ever be deleted? I'm learning about function decorators which, as my early studies tell me, depend on calling a function defined inside another function. This suggests that objects defined inside functions are never deleted, otherwise function decorators would never work. (I'm not 100% sure my understanding of function decorators is correct since I'm still learning about them). What's the right way to think about this?
