Common Mistakes

Importing pyplot instead of animation

Forgetting to import animation module

The animation module is needed to create animations in matplotlib.

Complete the code to create a figure object for the animation.

Matplotlib

fig = plt.[1]()

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

💡 Hint

Common Mistakes

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

Using plt.show() which only displays the plot

The figure() function creates a new figure window for plotting.

3fill in blank

hard

Fix the error in the animation function call to update the plot over time.

Matplotlib

ani = animation.FuncAnimation(fig, [1], frames=100, interval=50)

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

Cshow

Ddraw

💡 Hint

Common Mistakes

Passing plt.plot instead of an update function

Passing plt.show which does not update frames

The FuncAnimation needs a function that updates the plot each frame, here named update_plot.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that stores squares of numbers greater than 3.

Matplotlib

squares = {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

💡 Hint

Common Mistakes

Using the word itself instead of its length

Using less than instead of greater than

The comprehension stores the length of each word if the length is greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension filtering items with positive values and uppercase keys.

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.lower()

💡 Hint

Common Mistakes

Using lowercase keys instead of uppercase

Using less than or equal instead of greater than

This comprehension creates a dictionary with uppercase keys and values greater than zero.
