💡 Hint

Common Mistakes

Using axis(False) which is invalid.

Using set_visible(False) which hides the whole axes object.

To hide the axis including ticks and labels, use set_axis_off().

4fill in blank

Fill both blanks to set the title for the second subplot and adjust layout.

Matplotlib

axes[[1]].set_title('Second Image')
plt.[2]()

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

💡 Hint

Common Mistakes

Using the wrong subplot index.

Forgetting to call tight_layout to fix spacing.

The second subplot in a 2x2 grid is at row 1, column 0 (index [1, 0]). Use tight_layout() to adjust spacing.

5fill in blank

hard

Fill all three blanks to create a dictionary of images with their titles, filter images with width > 100, and display them.

Matplotlib

images = [1]
filtered = {title: img for title, img in images.items() if img.shape[[2]] [3] 100}
for ax, (title, img) in zip(axes.flatten(), filtered.items()):
    ax.imshow(img)
    ax.set_title(title)
plt.tight_layout()

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

💡 Hint

Common Mistakes

Using wrong dictionary syntax.

Using wrong index for image width.

Using wrong comparison operator.

Create a dictionary with image titles as keys. The width is the 1st dimension in img.shape. Filter images where width > 100.
