💡 Hint

Common Mistakes

Using a style name that is not installed or misspelled.

Forgetting to import matplotlib.pyplot as plt.

The plt.style.use() function sets the style for matplotlib plots. 'ggplot' is a popular style that mimics the ggplot2 style from R.

2fill in blank

medium

Complete the code to apply the 'seaborn-darkgrid' style to the plot.

Data Analysis Python

import matplotlib.pyplot as plt
plt.style.use('[1]')
plt.plot([10, 20, 30], [1, 4, 9])
plt.show()

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

💡 Hint

Common Mistakes

Using 'seaborn-dark' instead of 'seaborn-darkgrid'.

Not calling plt.show() to display the plot.

The 'seaborn-darkgrid' style adds a dark grid background to plots, improving readability.

3fill in blank

hard

Fix the error in the code to set the style to 'bmh'.

Data Analysis Python

import matplotlib.pyplot as plt
plt.style.[1]('bmh')
plt.plot([1, 2, 3], [3, 2, 1])
plt.show()

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

💡 Hint

Common Mistakes

Using a non-existent method like 'set_style' or 'apply'.

Calling plt.style as a function instead of using the 'use' method.

The correct function to set a style in matplotlib is plt.style.use().

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps each style name to its description length.

Data Analysis Python

styles = ['ggplot', 'bmh', 'seaborn-darkgrid']
descriptions = {style: len(style) for style in styles if style [1] '[2]'}

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

Astartswith

Bendswith

Cgg

Dgrid

💡 Hint

Common Mistakes

Using 'endswith' instead of 'startswith'.

Using the wrong substring to filter styles.

The code filters styles that start with 'gg' and creates a dictionary with style names and their length.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps style names to their uppercase form if they contain 'dark'.

Data Analysis Python

styles = ['ggplot', 'bmh', 'seaborn-darkgrid']
result = {style: style[1]() for style in styles if '[2]' [3] style}

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

Bdark

Cin

D.lower

Attempts:

💡 Hint

Common Mistakes

Using '.lower()' instead of '.upper()'.

Using '==' instead of 'in' to check substring presence.

The code checks if 'dark' is in the style name and maps it to its uppercase version.
