Verified usage

Verified import paths — ran on the pinned version, not inferred.

copy

✓ from zope.copy import copy

✗ from zope.copy import deepcopy

zope.copy does not have a 'deepcopy' function; use copy with hooks.

ICopyHook

✓ from zope.copy.interfaces import ICopyHook

Demonstrates basic copying of an object using zope.copy's copy function.

from zope.copy import copy from zope.interface import directlyProvides from zope.copy.interfaces import ICopyHook class MyObj: def __init__(self, value): self.value = value # Example usage obj = MyObj(42) obj_copy = copy(obj) print(obj_copy.value) # 42

Debug

Known issues

breakingzope.copy 6.0 removed support for Python 2 and Python versions <3.9.

fix

Ensure your environment uses Python >=3.9.

affects: >=6.0

gotchaThe copy function does not copy some built-in types (e.g., modules, functions, classes) by default; manual handling via ICopyHook adapters may be needed.

fix

Implement an ICopyHook for such types if deep copying is required.

affects: all

deprecatedUse of zope.copy's old-style super() calls may break with newer Python versions.

fix

Upgrade to zope.copy 6.0.

affects: <6.0

Errors

Common errors & fixes

AttributeError: 'module' object has no attribute 'copy'

Importing incorrectly as 'import zope.copy' and then calling 'zope.copy.copy()'.

fix

Use 'from zope.copy import copy'.

TypeError: object.__copy__() takes exactly one argument (the instance to copy)

Trying to use Python's built-in copy.copy on objects that expect zope.copy's copy.

fix

Use 'from zope.copy import copy' instead of 'import copy'.
