Answer:
I am writing the Python program:
lyrics = ["I wanna be your endgame", "I wanna be your first string",
"I wanna be your A-Team", "I wanna be your endgame, endgame"]
lines_of_sanity = 6
counter = 0
while counter <= lines_of_sanity+1:
for line in lyrics:
print(line)
counter = counter + 1
print("MAKE IT STOP")
Explanation:
- The lyrics is a list which has the following lines of song.
I wanna be your endgame
I wanna be your first string
I wanna be your A-Team
I wanna be your endgame, endgame
- The value of lines_of_sanity is 6.
- counter variable is initialized to 0.
- The while loop starts which keeps executing until the value of counter becomes greater than 6 which is the value of lines_of_sanity
- The for loop inside the while loop moves through each line of lyrics list and prints that line. The counter variable increments to 1 at each iteration.
- Lets see what the while and for loops print at each iteration:
1st iteration: counter = 0, following line is displayed:
- I wanna be your endgame
- Value of counter increments by 1.
- counter = 1
2nd iteration: counter = 1, following line is displayed:
- I wanna be your first string
- Value of counter increments by 1.
- counter = 2
3rd iteration: counter = 2, following line is displayed:
- I wanna be your A-Team
- Value of counter increments by 1.
- counter = 3
4th iteration: counter = 3, following line is displayed:
- I wanna be your endgame, endgame
- Value of counter increments by 1.
- counter = 4
5th iteration: counter = 4, following line is displayed:
- I wanna be your endgame
- Value of counter increments by 1.
- counter = 5
6th iteration: counter = 5, following line is displayed:
- I wanna be your first string
- Value of counter increments by 1.
- counter = 6
7th iteration: counter = 6, following line is displayed:
- I wanna be your A-Team
- Value of counter increments by 1.
- counter = 7
- The program should keep going to finish out the current verse. So following line is displayed:
- I wanna be your endgame, endgame
- The loop breaks as the value of counter = 7 is greater than lines_of_sanity i.e. 6
- So at last the print("MAKE IT STOP") statement is execute which displays the following line:
- MAKE IT STOP
- The program along with the output is attached.
