Multi-step reasoning in Prompt Engineering / GenAI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate the mean of a list of numbers.

Prompt Engineering / GenAI

numbers = [4, 8, 15, 16, 23, 42]
mean = sum(numbers) / [1]

Bsum(numbers)

Cmax(numbers)

Dlen(numbers)

💡 Hint

Common Mistakes

Dividing by sum(numbers) instead of the count.

Using max(numbers) or min(numbers) which are unrelated.

The mean is the sum of all numbers divided by the count of numbers, which is given by len(numbers).

medium

Complete the code to split data into features and labels for training.

Prompt Engineering / GenAI

data = [[5.1, 3.5, 1.4, 0.2, 'setosa'], [6.2, 3.4, 5.4, 2.3, 'virginica']]
features = [row[:[1]] for row in data]
labels = [row[-1] for row in data]

💡 Hint

Common Mistakes

Using 3 which misses one feature.

Using 5 which includes the label.

The features are the first 4 elements in each row, so we slice up to index 4.

hard

Fix the error in the code to train a simple linear regression model using scikit-learn.

Prompt Engineering / GenAI

from sklearn.linear_model import LinearRegression
X = [[1], [2], [3], [4]]
y = [2, 4, 6, 8]
model = LinearRegression()
model.[1](X, y)

💡 Hint

Common Mistakes

Using train which is not a method in scikit-learn.

Using predict which is for making predictions, not training.

The fit method trains the model on the data.

4fill in blank

hard

Fill both blanks to create a dictionary of word lengths for words longer than 3 characters.

Prompt Engineering / GenAI

words = ['apple', 'bat', 'carrot', 'dog']
lengths = {word: [1] for word in words if len(word) [2] 3}

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

Alen(word)

C<

Dword

💡 Hint

Common Mistakes

Using word as the value instead of its length.

Using '<' which selects shorter words.

We want the length of each word as the value, and only include words longer than 3 characters.

5fill in blank

hard

Fill all three blanks to filter a dictionary for items with values greater than 10 and convert keys to uppercase.

Prompt Engineering / GenAI

data = {'a': 5, 'b': 15, 'c': 25}
filtered = { [1]: [2] for [3], v in data.items() if v > 10 }

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

💡 Hint

Common Mistakes

Using data instead of loop variable for keys.

Not converting keys to uppercase.

The keys are converted to uppercase with k.upper(), values are v, and the loop variables are k and v.
