Fig, ax = plt.subplots pattern in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a figure and axes using plt.subplots.

Matplotlib

fig, ax = plt.[1]()

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

Bplot

Csubplots

Dshow

💡 Hint

Common Mistakes

Using plt.plot() instead of plt.subplots()

Using plt.figure() which returns only the figure, not axes

Trying to call plt.show() here which displays the plot

The plt.subplots() function creates a figure and axes objects together.

2fill in blank

medium

Complete the code to plot a line on the axes object.

Matplotlib

fig, ax = plt.subplots()
ax.[1]([1, 2, 3], [4, 5, 6])

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

💡 Hint

Common Mistakes

Using ax.scatter() which draws points, not lines

Using ax.hist() which draws histograms

Using ax.bar() which draws bar charts

The ax.plot() method draws a line plot on the axes.

3fill in blank

hard

Fix the error in the code to set the title of the axes.

Matplotlib

fig, ax = plt.subplots()
ax.set_[1]('My Plot Title')

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

Aylabel

Btitle

Cxlabel

Dlegend

Attempts:

💡 Hint

Common Mistakes

Using set_xlabel or set_ylabel which label axes, not title

Using set_legend which controls the legend

The method ax.set_title() sets the title of the plot.

4fill in blank

hard

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

Matplotlib

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<

Dword

Attempts:

3 left

💡 Hint

Common Mistakes

Using < instead of > in the condition

Mapping word to word instead of length

Using len(word) in the condition but not in the value

The dictionary comprehension maps each word to its length if the length is greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase words to their values if the value is greater than 0.

Matplotlib

result = { [1]: [2] for k, v in data.items() if v [3] 0 }

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

Ak.upper()

Bv

C>

Dk

💡 Hint

Common Mistakes

Using original key without uppercasing

Using wrong comparison operator like <

Using key instead of value in the dictionary values

This comprehension creates a dictionary with keys as uppercase versions of original keys and values where the value is positive.
