The answer is D. The program prints:
Time to recharge!
Why?
Python checks the conditions from the top and runs the first one that is true. Is 6 > 9? No. Is 6 > 8? No. Neither was true, so the else part runs.
Trace table
A trace table follows the program step by step. Here’s this one:
| question | answer |
|---|---|
| battery > 9 | False |
| battery > 8 | False |
The code again
battery = 6
if battery > 9:
print("Full speed ahead!")
elif battery > 8:
print("Slow and steady.")
else:
print("Time to recharge!")Try it: change one number in the program and predict the new output before you run it.
