Answer: Python Puzzler #747

The answer is B. The program prints:

Level 10

Checked by running the program for real.

Python works out level + 2 first, which is 10. str() turns the number into text so it can be joined onto “Level “.

level = 8
print("Level " + str(level + 2))

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