any() and all() functions in Python - Mini Project: Build & Apply

Using any() and all() Functions in Python

📖 Scenario: You are working on a simple quality check system for a small factory. Each product is checked for several quality points, and you want to quickly find out if any product failed any check or if all products passed all checks.

🎯 Goal: Build a Python program that uses the any() and all() functions to check product quality results.

📋 What You'll Learn

Create a list called quality_checks with boolean values representing pass (True) or fail (False) for each product.

Create a variable called threshold to represent the minimum number of products that must pass.

Use the any() function to check if any product failed the quality check.

Use the all() function to check if all products passed the quality check.

Print the results clearly.

💡 Why This Matters

🌍 Real World

Quality control in factories often requires quick checks to see if any items failed or if all items passed certain tests.

💼 Career

Understanding any() and all() helps in data validation, filtering, and decision-making tasks common in software development and data analysis.

1

Create the quality check list

Create a list called quality_checks with these exact boolean values: True, True, False, True, True.

Python

# Create the list quality_checks with True, True, False, True, True
# Your code here

Need a hint?

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

2

Set the threshold for passing products

Create a variable called threshold and set it to the integer 4.

Python

quality_checks = [True, True, False, True, True]
# Create a variable threshold and set it to 4
# Your code here

Need a hint?

Use a simple assignment statement with the variable name threshold.

3

Check if any product failed and if all passed

Create a variable called any_failed that uses any() on the negation of quality_checks to check if any product failed. Then create a variable called all_passed that uses all() on quality_checks to check if all products passed.

Python

quality_checks = [True, True, False, True, True]
threshold = 4
# Create any_failed using any() on the negation of quality_checks
# Create all_passed using all() on quality_checks
# Your code here

Need a hint?

Use a generator expression inside any() to check for False values by negating each check.

4

Print the results

Print the values of any_failed and all_passed with clear messages using print().

Python

quality_checks = [True, True, False, True, True]
threshold = 4
any_failed = any(not check for check in quality_checks)
all_passed = all(quality_checks)
# Print the results with clear messages
# Your code here

Need a hint?

Use f-strings to include variable values inside the printed messages.
