📘 Python Crash Course – Chapter 4: Working With Lists – Exercise 4-6 Solution
Welcome to another solution from Python Crash Course by Eric Matthes.
📝 Exercise 4-6
Task:
Store a message in a variable, and then print that message.Use the third argument of the range() function to make a list of the odd numbers from 1 to 20 .
Use a for loop to print each number
✅ Solution Code:
num=list(range(1,21,2))
for no in num:
print(no)
🧠 Code Explanation:
This Python code demonstrates how to generate a list of odd numbers and iterate through it using a for loop. Here's how it works:
-
Create a list of odd numbers:
The
range(1, 21, 2)function generates a sequence of numbers starting from 1, ending before 21, and incrementing by 2. This ensures that only odd numbers between 1 and 20 are included. Thelist()function converts this range into a list, which is stored in the variablenum. -
Iterate through the list:
A
forloop is used to iterate through each number in thenumlist. The variablenotakes 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.
