📘 Python Crash Course – Chapter 4: Working With Lists – Exercise 4-7 Solution

Welcome to another solution from Python Crash Course by Eric Matthes.

📝 Exercise 4-7

Task:
Make a list of the multiples of 3 from 3 to 30 . Use a for loop to print the numbers in your list

✅ Solution Code:


l = list(range(3,31,3))
for no in l:
    print(no)

🧠 Code Explanation:

This Python code demonstrates how to generate a list of multiples of 3 and iterate through it using a for loop. Here's how it works:

  1. Create a list of multiples of 3:

    The range(3, 31, 3) function generates a sequence of numbers starting from 3, ending before 31, and incrementing by 3. This ensures that only multiples of 3 between 3 and 30 are included. The list() function converts this range into a list, which is stored in the variable l.

  2. Iterate through the list:

    A for loop is used to iterate through each number in the l list. The variable no takes on each value in the list, one at a time.

This code demonstrates how to use the third argument of the range() function to generate a sequence with a specific step size and how to iterate through the resulting list.
