I have a dataframe:
s1 = pd.Series([5, 6, 7]) s2 = pd.Series([7, 8, 9]) df = pd.DataFrame([list(s1), list(s2)], columns = ["A", "B", "C"]) A B C 0 5 6 7 1 7 8 9 [2 rows x 3 columns]
and I need to add a first row [2, 3, 4] to get:
A B C 0 2 3 4 1 5 6 7 2 7 8 9
I’ve tried append()
and concat()
functions but can’t find the right way how to do that.
