New submission from Erlend E. Aasland <[email protected]>:
Currently, the sqlite3.Statement type is not exposed in the module dict:
>>> import sqlite3
>>> sqlite3.Statement
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/sqlite3/__init__.py",
line 37, in __getattr__
raise AttributeError(f"module 'sqlite3' has no attribute '{name}'")
AttributeError: module 'sqlite3' has no attribute 'Statement'
It is possible to extract it using this trick:
>>> cx = sqlite3.connect(":memory:")
>>> stmt = cx("select 1")
>>> type(stmt)
<class 'sqlite3.Statement'>
>>> type(stmt)()
<sqlite3.Statement object at 0x109006b30>
There is no use case for this; statement objects belong to the internal
workings of the sqlite3 module. I suggest adding
Py_TPFLAGS_DISALLOW_INSTANTIATION to make this fact more explicit.
