Answer: Python Puzzler #819

The answer is C. The program prints:

Level 16

Checked by running the program for real.

Python works out level + 9 first, which is 16. str() turns the number into text so it can be joined onto “Level “.

level = 7
print("Level " + str(level + 9))

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