python - How to use mode() in pandas?

Question

As shown in the title, how to use mode() in pandas? I didn’t understand the official introduction, as follows

>>> df = pd.DataFrame({'A': [1, 2, 1, 2, 1, 2, 3]})
>>> df.mode()
   A
0  1
1  2

Answer 1

mode should be the mode, which is the one with the highest frequency. In the example, 1 and 2 both appear three times, which are the most frequent, so these two numbers are returned.
