The answer is D. The program prints:
OBO
This answer was checked by running the program for real.
Why?
word[1:4] is a slice: it starts at position 1 and stops before position 4. Positions count from 0.
Trace table
A trace table follows the program step by step. Here’s this one:
| position | letter |
|---|---|
| 0 | R |
| 1 | O |
| 2 | B |
| 3 | O |
| 4 | T |
| 5 | I |
| 6 | C |
| 7 | S |
The code again
word = "ROBOTICS"
print(word[1:4])Try it: change one number in the program and predict the new output before you run it.
