Matplotlib pie chart

You are given a task to design a doughnut chart that represents the proportion of students enrolled in different programming courses. Fill in the blank so that the chart looks as follows:

import matplotlib.pyplot as plt

plt.figure(figsize=(10, 6))
plt.pie([17, 14, 12, 5], 
        labels=['C', 'Python', 'Java' ,'PHP'], 
        colors=['teal', 'skyblue', 'darkorange', 'gold'], 
        wedgeprops={'width':0.2}, 
        # your code here
        )

plt.title('Students enrolled in programming classes')
plt.show()

Tip: Each slice is 3% away from the main pie chart.
