con = sqlite3.connect(":memory:")
cur = con.execute("CREATE TABLE lang(name, first_appeared)")
# This is the qmark style:
cur.execute("INSERT INTO lang VALUES(?, ?)", ("C", 1972))
# This is the named style used with executemany():
data = (
{"name": "C", "year": 1972},
{"name": "Fortran", "year": 1957},

("Python", 1991),
("Go", 2009),
]
cur.executemany("INSERT INTO lang VALUES(?, ?)", lang_list)
# And this is the named style:
cur.execute("SELECT * FROM lang WHERE first_appeared = :year", {"year": 1972})

params = (1972,)
cur.execute("SELECT * FROM lang WHERE first_appeared = ?", params)
print(cur.fetchall())
