How to display the value of each bar in multi bar barcharts per row

Question

Iam tring to display the value of each bar, problem is that for each row there is 3 columns therefore 3 bars per row

So i can't just use this following code

import matplotlib.pyplot as plt
for i, v in enumerate(df.values):      
       plt.text(i, v, str(v), color='blue', fontweight='bold')

---

and results in error when try to df.plot() saying TypeError: only size-1 arrays can be converted to Python scalars

---

That's the df

import pandas as pd
df = pd.read_csv('https://cocl.us/datascience_survey_data')
df = df.set_index('Unnamed: 0')
df = df.sort_values(['Very interested'], ascending=False)
df = df / 2233 * 100
df = round(df, 2)

---

---

This is my current plot

df.plot(kind='bar', color=['#5cb85c', '#5bc0de', '#d9534f'], width=0.8, figsize=(10, 8))

---

That's what iam tring to acheive
