Pie chart color customization in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the colors of the pie chart slices.

Matplotlib

import matplotlib.pyplot as plt
sizes = [15, 30, 45, 10]
colors = [1]
plt.pie(sizes, colors=colors)
plt.show()

Drag options to blanks, or click blank then click option'

A['red', 'blue', 'green', 'yellow']

B['circle', 'square', 'triangle', 'star']

C[15, 30, 45, 10]

D['apple', 'banana', 'cherry', 'date']

💡 Hint

Common Mistakes

Using shapes or numbers instead of color names.

Passing the sizes list as colors.

The colors parameter expects a list of color names or codes. Option A provides valid color names.

2fill in blank

medium

Complete the code to add labels and set custom colors for the pie chart.

Matplotlib

import matplotlib.pyplot as plt
sizes = [20, 25, 35, 20]
labels = ['A', 'B', 'C', 'D']
colors = [1]
plt.pie(sizes, labels=labels, colors=colors)
plt.show()

Drag options to blanks, or click blank then click option'

A['circle', 'square', 'triangle', 'star']

B['cyan', 'magenta', 'yellow', 'black']

C['red', 'green', 'blue']

D[20, 25, 35, 20]

💡 Hint

Common Mistakes

Using fewer colors than slices.

Using invalid color names or shapes.

The colors list must match the number of slices and contain valid color names. Option B is correct.

3fill in blank

hard

Fix the error in the code to correctly set the pie chart colors.

Matplotlib

import matplotlib.pyplot as plt
sizes = [10, 40, 30, 20]
colors = ['red', 'blue', 'green']
plt.pie(sizes, colors=[1])
plt.show()

Drag options to blanks, or click blank then click option'

A['red', 'blue', 'green', 'yellow']

Bsizes

Ccolors

D['red', 'blue']

💡 Hint

Common Mistakes

Using a colors list shorter than sizes list.

Passing sizes as colors.

The colors list must have the same length as sizes. Option A fixes the error by adding a fourth color.

4fill in blank

hard

Fill both blanks to create a pie chart with exploded slices and custom colors.

Matplotlib

import matplotlib.pyplot as plt
sizes = [25, 35, 20, 20]
colors = [1]
explode = [2]
plt.pie(sizes, colors=colors, explode=explode)
plt.show()

Drag options to blanks, or click blank then click option'

A['gold', 'lightcoral', 'lightskyblue', 'yellowgreen']

B[0.1, 0, 0, 0]

C['red', 'blue', 'green', 'yellow']

D[1, 1, 1, 1]

💡 Hint

Common Mistakes

Using explode values outside 0 to 1 range.

Mismatch between colors and sizes length.

Option A sets custom colors, and option B explodes the first slice only.

5fill in blank

hard

Fill all three blanks to create a pie chart with labels, custom colors, and exploded slices.

Matplotlib

import matplotlib.pyplot as plt
sizes = [30, 20, 25, 25]
labels = [1]
colors = [2]
explode = [3]
plt.pie(sizes, labels=labels, colors=colors, explode=explode)
plt.show()

Drag options to blanks, or click blank then click option'

A['Apples', 'Bananas', 'Cherries', 'Dates']

B['#ff9999', '#66b3ff', '#99ff99', '#ffcc99']

C[0, 0.1, 0, 0]

D['red', 'blue', 'green']

💡 Hint

Common Mistakes

Using fewer colors than slices.

Exploding all slices instead of one.

Labels are set with option A, colors with option B (hex codes), and explode with option C to highlight the second slice.
