The answer is D. The program prints:
Level 15
This answer was checked by running the program for real.
Why?
Python works out level + 8 first, which is 15. str() turns the number into text so it can be joined onto “Level “.
The code again
level = 7
print("Level " + str(level + 8))
Try it: change one number in the program and predict the new output before you run it.
