List comprehension with if–else in Python - Mini Project: Build & Apply

List comprehension with if-else

📖 Scenario: You are working in a fruit store. You have a list of fruit names. You want to create a new list that shows if each fruit is 'Sweet' or 'Sour'. For this, you will use list comprehension with an if-else condition.

🎯 Goal: Create a list of fruits, then use list comprehension with if-else to label each fruit as 'Sweet' or 'Sour'. Finally, print the new list.

📋 What You'll Learn

Create a list called fruits with these exact values: 'apple', 'lemon', 'banana', 'lime', 'cherry'

Create a list comprehension called taste_labels that labels each fruit as 'Sweet' if the fruit is 'apple', 'banana', or 'cherry', otherwise 'Sour'

Print the taste_labels list

💡 Why This Matters

🌍 Real World

Stores and shops often need to categorize items quickly based on properties like taste, price, or availability. Using list comprehension with if-else helps automate this.

💼 Career

Understanding list comprehension with conditions is useful for data processing, filtering, and labeling tasks in many programming jobs.

1

Create the list of fruits

Create a list called fruits with these exact values: 'apple', 'lemon', 'banana', 'lime', 'cherry'

Python

# Create the list called fruits with the exact fruit names
# Your code here

Need a hint?

Use square brackets [] to create a list and separate items with commas.

2

Set up the sweet fruits list

Create a list called sweet_fruits that contains these exact fruits: 'apple', 'banana', 'cherry'

Python

fruits = ['apple', 'lemon', 'banana', 'lime', 'cherry']
# Create the list called sweet_fruits with the exact fruit names
# Your code here

Need a hint?

This list will help you check if a fruit is sweet or sour.

3

Create the list comprehension with if-else

Create a list comprehension called taste_labels that goes through each fruit in fruits and adds 'Sweet' if the fruit is in sweet_fruits, otherwise adds 'Sour'

Python

fruits = ['apple', 'lemon', 'banana', 'lime', 'cherry']
sweet_fruits = ['apple', 'banana', 'cherry']
# Create the list comprehension taste_labels with if-else
# Your code here

Need a hint?

Use the format: [value_if_true if condition else value_if_false for item in list]

4

Print the taste labels

Write a print statement to display the taste_labels list

Python

fruits = ['apple', 'lemon', 'banana', 'lime', 'cherry']
sweet_fruits = ['apple', 'banana', 'cherry']
taste_labels = ['Sweet' if fruit in sweet_fruits else 'Sour' for fruit in fruits]
# Print the taste_labels list
# Your code here

Need a hint?

Use print(taste_labels) to show the result.
