Practice - 5 Tasks

1fill in blank

💡 Hint

Common Mistakes

Using dtype instead of shape, which gives data type not dimensions.

Using size, which gives total number of elements, not the shape.

The shape property gives the dimensions of the image array, such as height, width, and channels.

Complete the code to find the data type of the image pixels.

Computer Vision

💡 Hint

Common Mistakes

Using shape instead of dtype, which gives dimensions not data type.

Using type(), which returns the Python type of the object, not the array data type.

The dtype property tells you the data type of the image pixels, like uint8 or float32.

Fix the error in the code to get the total number of pixels in the image.

Computer Vision

total_pixels = image.[1]

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

💡 Hint

Common Mistakes

Using shape, which returns a tuple of dimensions, not a single number.

Using len, which only returns the size of the first dimension.

The size property returns the total number of elements (pixels) in the image array.

4fill in blank

hard

Fill both blanks to create a dictionary with image shape and data type.

Computer Vision

image_info = {'shape': image.[1], 'dtype': image.[2]

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

💡 Hint

Common Mistakes

Swapping shape and dtype properties.

Using size or type instead of dtype.

This dictionary stores the image's dimensions under 'shape' and the pixel data type under 'dtype'.

5fill in blank

hard

Fill all three blanks to create a summary string with image shape, data type, and total pixels.

Computer Vision

summary = f"Shape: {image.[1], Type: {image.[2], Pixels: {image.[3]"

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

Mixing up size and shape.

This string shows the image's shape, data type, and total number of pixels for a quick overview.
