Nested for loop execution in Python - Mini Project: Build & Apply

Nested for loop execution

📖 Scenario: You are organizing a small event and want to create a seating chart. You have a list of tables and a list of guests. You want to pair each guest with each table to see all possible seating options.

🎯 Goal: Build a program that uses nested for loops to print every combination of tables and guests.

📋 What You'll Learn

Create a list called tables with the values 'Table 1', 'Table 2', and 'Table 3'

Create a list called guests with the values 'Alice', 'Bob', and 'Charlie'

Use a nested for loop with variables table and guest to iterate over tables and guests

Print each combination in the format: Guest Alice sits at Table 1

💡 Why This Matters

🌍 Real World

Event planners often need to consider all seating options to organize guests efficiently.

💼 Career

Understanding nested loops is essential for tasks like scheduling, pairing data, and generating combinations in programming jobs.

1

Create the tables list

Create a list called tables with these exact values: 'Table 1', 'Table 2', and 'Table 3'

Python

# Create the list tables with 'Table 1', 'Table 2', and 'Table 3'
tables = []  # Your code here

Need a hint?

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

2

Create the guests list

Create a list called guests with these exact values: 'Alice', 'Bob', and 'Charlie'

Python

tables = ['Table 1', 'Table 2', 'Table 3']
# Create the list guests with 'Alice', 'Bob', and 'Charlie'
guests = []  # Your code here

Need a hint?

Use the same list syntax as before to create the guests list.

3

Write the nested for loops

Use nested for loops with variables table and guest to iterate over tables and guests respectively

Python

tables = ['Table 1', 'Table 2', 'Table 3']
guests = ['Alice', 'Bob', 'Charlie']
# Use nested for loops to go through tables and guests
for table in tables:
    for guest in guests:
        pass  # Your code here

Need a hint?

Write one for loop inside another. The inner loop goes through guests.

4

Print each seating combination

Inside the nested loops, write a print statement to display: Guest {guest} sits at {table} using an f-string

Python

tables = ['Table 1', 'Table 2', 'Table 3']
guests = ['Alice', 'Bob', 'Charlie']
for table in tables:
    for guest in guests:
        # Print the seating arrangement
        # Your code here

Need a hint?

Use print(f"Guest {guest} sits at {table}") inside the inner loop.
