# Generate betweenness centrality for retweets
rt_centrality = ____
# Generate betweenness centrality for replies
reply_centrality = ____
# Store centralities in data frames
rt = pd.DataFrame(____, ____ = ____)
reply = pd.DataFrame(____, ____ = ____)
# Print first five results in descending order of centrality
print(rt.sort_values('betweenness_centrality', ascending = False).head())
# Print first five results in descending order of centrality
print(reply.sort_values('betweenness_centrality', ascending = False).head())
