print(s[1] * s.index("n"))
```
Options:
- A. yyyy
- B. 55555
- C. y5
- D. TypeError
---
**Detailed Explanation:**
For Question 17, the key is to understand tuple slicing in Python:
- `tupl1[:-1]` returns all elements except the last one: `(5, 3, 1, 9)`.
- `tupl1[0:5]` returns the first five elements: `(5, 3, 1, 9, 0)`.
- `tupl1[0:4]` returns the first four elements: `(5, 3, 1, 9)`.
- `tupl1[-4:]` returns the elements from index -4 to the end: `(3, 1, 9, 0)`.
Hence, the correct answer is A. i, iii.
For Question 18, the string `s = "python is awesome"` and `s[2]` is `](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9d8ec6fd-e2f0-4680-809b-ff80bf35e76d%2Fadb69cac-34c4-4343-a238-d3a2e2adb434%2F0vj3qw_processed.jpeg&w=3840&q=75)
