The answer is D. The program prints:
5
Why?
len counts every character, including spaces and punctuation. ‘robot’ has 5.
Trace table
A trace table follows the program step by step. Here’s this one:
| count | character |
|---|---|
| 1 | r |
| 2 | o |
| 3 | b |
| 4 | o |
| 5 | t |
The code again
word = "robot"
print(len(word))Try it: change one number in the program and predict the new output before you run it.
