Answer: Python Puzzler #564

The answer is C. The program prints:

Level 15

Checked by running the program for real.

Python works out level + 6 first, which is 15. str() turns the number into text so it can be joined onto “Level “.

level = 9
print("Level " + str(level + 6))

Try it: change one number in the program and predict the new output before you run it.
