Sure, let's verify:
>>> import sqlite3
>>> conn = sqlite3.connect(":memory:")
>>> cur = conn.cursor()
>>> cur.execute("create table t1(c1 varchar(20))")
<sqlite3.Cursor object at 0xb7ecec20>
>>> cur.execute("insert into t1(c1) values('?')")
<sqlite3.Cursor object at 0xb7ecec20>
>>> cur.execute("select * from t1").fetchall()
[(u'?',)]
>>> cur.execute("insert into t1(c1) values(?)")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
sqlite3.ProgrammingError: Incorrect number of bindings supplied. The
current statement uses 1, and there are 0 supplied.
Maybe I'm misunderstanding what you mean by "behave this way", but it
certainly looks like it's doing what I described as "Don't treat things
that look like parameter markers as parameter markers if they appear
inside apostrophes."
