Chapter 4: Problem 11

Write a for loop that displays all of the odd numbers, 1 through 49.

Short Answer

Expert verified

**Question:** Write a for loop that displays all of the odd numbers between 1 and 49, inclusive, while explaining the steps involved in creating a for loop. **Answer:** To create a for loop that displays all odd numbers from 1 to 49, first initialize the loop counter (n) to 1. The loop should continue executing as long as n is less than or equal to 49. Increment the loop counter (n) by 2, so we only check odd numbers, as adding 2 to an odd number will result in another odd number. Within the loop, print the current value of n, which is guaranteed to be an odd number. The completed for loop should look like this: ```python for n in range(1, 50, 2): print(n) ```

Step by step solution

Initialize loop counter

Start by initializing the loop counter (n) to 1, as the first odd number we want to display is 1.

Loop Condition

The loop should continue executing as long as the loop counter (n) is less than or equal to 49, as 49 is the last odd number we want to display.

Increment the loop counter

Increment the loop counter (n) by 2 after every iteration of the loop. This ensures that we only check odd numbers, as adding 2 to an odd number will always result in another odd number.

Display odd numbers

Within the loop, print the current value of the loop counter (n), as it is guaranteed to be an odd number due to the way we've set up the loop.

Complete For Loop

Combine the steps above to create the final for loop, which will display all of the odd numbers from 1 through 49. The complete code should look like this: ```python for n in range(1, 50, 2): print(n) ```
