Tick marks and tick labels in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the x-axis tick labels to ['A', 'B', 'C'].

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.xticks([1, 2, 3], [1])
plt.show()

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

A['A', 'B', 'C']

B[1, 2, 3]

C['X', 'Y', 'Z']

D['4', '5', '6']

💡 Hint

Common Mistakes

Using the tick positions list instead of labels.

Not matching the number of labels to tick positions.

The plt.xticks() function sets the positions and labels of the x-axis ticks. Here, the labels are set to ['A', 'B', 'C'].

2fill in blank

medium

Complete the code to set the y-axis ticks at positions 0, 5, and 10.

Matplotlib

import matplotlib.pyplot as plt
plt.plot([0, 1, 2], [0, 5, 10])
plt.yticks([1])
plt.show()

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

A[1, 2, 3]

B[0, 5, 10]

C['0', '5', '10']

D[0, 1, 2]

💡 Hint

Common Mistakes

Using strings instead of numbers for tick positions.

Setting ticks outside the data range.

The plt.yticks() function sets the positions of the y-axis ticks. Here, ticks are set at 0, 5, and 10.

3fill in blank

hard

Fix the error in the code to correctly set x-axis tick labels to ['Low', 'Medium', 'High'].

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [10, 20, 30])
plt.xticks([1, 2, 3], [1])
plt.show()

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

A['10', '20', '30']

B['low', 'medium', 'high']

C[1, 2, 3]

D['Low', 'Medium', 'High']

💡 Hint

Common Mistakes

Using numbers instead of strings for labels.

Mismatching the number of labels and tick positions.

The plt.xticks() function requires the second argument to be a list of labels matching the tick positions. Using ['Low', 'Medium', 'High'] sets the labels correctly.

4fill in blank

hard

Fill both blanks to create a dictionary of word lengths for words longer than 3 letters.

Matplotlib

words = ['apple', 'bat', 'carrot', 'dog']
lengths = {word: [1] for word in words if len(word) [2] 3}

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

Alen(word)

B==

C>

D<=

💡 Hint

Common Mistakes

Using the wrong comparison operator.

Using the word itself instead of its length.

The dictionary comprehension maps each word to its length using len(word). The condition len(word) > 3 filters words longer than 3 letters.

5fill in blank

hard

Fill all three blanks to create a dictionary of uppercase words and their lengths for words longer than 3 letters.

Matplotlib

words = ['apple', 'bat', 'carrot', 'dog']
result = [1]: [2] for w in words if len(w) [3] 3}

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

Aw.upper()

Blen(w)

C>

Dw

💡 Hint

Common Mistakes

Using the original word instead of uppercase.

Using the wrong comparison operator.

The dictionary comprehension uses w.upper() as keys and len(w) as values. The condition len(w) > 3 filters words longer than 3 letters.
