Please answer #1 using Python and Pandas, thx

Problem 1 Write a function called group_means that takes its input a Pandas DataFrame with exactly the columns: "labels" and "weights". Group entries by labels and return the average weights for each label. Make sure to name the column in the returned data frame "average weight" and use the "labels" as the index, but don't name the index column. Example: See an example by executing the code in the second cell below. : import pandas as pd import numpy as np from IPython.display import display def group_means (X): # YOUR CODE HERE raise NotImplementedError() : # YOUR CODE HERE raise NotImplementedError()
