This code implements a countdown that prints numbers from 10 to 1 and then displays "Go Go Go!" at the end. Here's a step-by-step explanation of what it does:

1. Initialize a variable: count_down is set to 10.

2. While Loop: The while loop checks if count_down >= 1. As long as this condition is true, the loop will execute.

3. Print the countdown: Inside the loop, it prints the value of count_down.

4. Decrement the variable: The line count_down = count_down - 1 decreases the value of count_down by 1 on every iteration.

5. End of loop: When count_down becomes less than 1, the while loop stops executing.

6. Final message: After the loop, the program prints Go Go Go!.

Output of the code:

10
9
8
7
6
5
4
3
2
1
Go Go Go!

Note:

There is a syntax error in the code. The string Go Go Go! is missing a closing quotation mark. It should be:

print('Go Go Go!')
