Passing sizes instead of labels for labels parameter.

Using incorrect format strings for autopct.

Use the labels variable for labels and '%1.1f%%' to show percentages with one decimal.

5fill in blank

Fill all three blanks to create a pie chart with labels, explode effect, and shadow.

Matplotlib

sizes = [15, 30, 55]
labels = ['Red', 'Blue', 'Green']
explode = ([1], [2], [3])
plt.pie(sizes, labels=labels, explode=explode, shadow=True)
plt.show()

💡 Hint

Common Mistakes

Using integers like 1 which offset too much.

Not using a tuple for explode.

The explode tuple offsets the first slice by 0.1 and leaves others unchanged with 0.
