1fill in blank

easy

Complete the code to clip the values in the array to a minimum of 0.

NumPy

💡 Hint

Common Mistakes

Using None as minimum value causes error.

Using a positive number greater than 0 clips too many values.

np.clip() limits values below the minimum to the minimum value. Here, minimum is 0.

medium

Complete the code to clip the values in the array between 2 and 8.

NumPy

import numpy as np
arr = np.array([1, 3, 5, 9])
clipped = np.clip(arr, [1], 8)
print(clipped)

💡 Hint

Common Mistakes

Setting minimum to 0 clips too many values.

Setting minimum higher than 2 clips values incorrectly.

Setting minimum to 2 and maximum to 8 clips values below 2 to 2 and above 8 to 8.

💡 Hint

Common Mistakes

Using a maximum bound larger than 4.

Using a minimum bound larger than maximum.

The maximum bound should be 4 to clip values above 4 down to 4.

Fill both blanks to clip values below 10 to 10 and above 20 to 20.

NumPy

import numpy as np
arr = np.array([5, 10, 15, 25])
clipped = np.clip(arr, [1], [2])
print(clipped)

💡 Hint

Common Mistakes

Swapping minimum and maximum values.

Using values outside the specified range.

Minimum is 10 and maximum is 20 to clip values outside this range.

hard

Fill all three blanks to create a dictionary with words as keys and their lengths clipped to max 4.

NumPy

words = ['apple', 'bat', 'cat', 'dolphin']
lengths = {word: len(word) if len(word) < [1] else [2] for word in words if len(word) > [3]
print(lengths)

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

💡 Hint

Common Mistakes

Using inconsistent max length values.

Filtering words incorrectly.

Clip lengths to max 4: if length less than 4, keep it; else set to 4. Include words longer than 3.
