Line plots in Data Analysis Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a simple line plot using matplotlib.

Data Analysis Python

import matplotlib.pyplot as plt

data = [1, 3, 2, 5, 7]
plt.[1](data)
plt.show()

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

💡 Hint

Common Mistakes

Using 'scatter' instead of 'plot' which creates a scatter plot.

Using 'bar' which creates bar charts, not line plots.

The plot function draws a line plot connecting the data points.

2fill in blank

medium

Complete the code to add labels to the x-axis and y-axis of the line plot.

Data Analysis Python

import matplotlib.pyplot as plt

data = [2, 4, 6, 8]
plt.plot(data)
plt.xlabel([1])
plt.ylabel('Value')
plt.show()

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

A'Time'

BValue

C'X-axis'

💡 Hint

Common Mistakes

Not using quotes around the label text.

Using the wrong label that does not describe the x-axis.

The xlabel function sets the label for the x-axis. It needs a string like 'Time'.

3fill in blank

hard

Fix the error in the code to correctly plot two lines on the same graph.

Data Analysis Python

import matplotlib.pyplot as plt

x = [1, 2, 3]
y1 = [2, 4, 6]
y2 = [1, 3, 5]
plt.plot(x, y1)
plt.plot(x, [1])
plt.show()

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

💡 Hint

Common Mistakes

Using the first y-values list twice.

Using x instead of y-values for the second plot.

To plot the second line, use the second y-values list y2 with the same x-values.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps words to their lengths only if length is greater than 3.

Data Analysis Python

words = ['data', 'science', 'is', 'fun']
lengths = {word: [1] for word in words if [2]

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

Alen(word)

Blen(word) > 3

Cword

Dword > 3

Attempts:

💡 Hint

Common Mistakes

Using the word itself as the value instead of its length.

Using the word variable in the condition instead of its length.

The dictionary comprehension maps each word to its length using len(word). The condition filters words with length greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase words to their lengths only if length is greater than 3.

Data Analysis Python

words = ['data', 'science', 'is', 'fun']
lengths = { [1]: [2] for word in words if [3] }

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

Aword.upper()

Blen(word)

Clen(word) > 3

Dword

Attempts:

3 left

💡 Hint

Common Mistakes

Not converting words to uppercase for keys.

Using the word itself as the value instead of its length.

Incorrect condition in the if clause.

The dictionary comprehension uses word.upper() as keys, maps to len(word), and filters words with length greater than 3.
