I want to plot bar graph using python seaborn library:

I tried it like the following
bar_plot = sns.barplot(x = 'source_city', y = 'price', hue = 'class', data = df)

Fetching bar labels

for labels in bar_plot.containers: bar_plot.bar_label(labels)

But in place of the values(price) I want the percentage(price) as bar label
How to do that, please guide.
Can I use estimator parameter, If so, how?
