	def test_insert_newvalues() -> None:
	df = pd.DataFrame({"a": [1, 2]})
	ab = pd.DataFrame({"col1": [1, 2], "col2": [3, 4]})
	ef = pd.DataFrame({"z": [4, 5, 6]})
	assert assert_type(df.insert(loc=0, column="b", value=None), None) is None
	assert assert_type(ab.insert(loc=0, column="newcol", value=[99, 99]), None) is None
	assert assert_type(ef.insert(loc=0, column="g", value=4), None) is None

column just wasn't typed
