1. Find the output of the following Python code:

(a) def square(x): (b) def divide(a, b):
return x * x return a / b
result = square(4) answer = divide(10, 2)
print(result) print(answer)

Output: Output:
(c) numbers = [10, 20, 30] (d) word = "Python"

numbers.remove(20) print(word[0:3])
print(numbers) print(word[::-1])
Output: Output:

2. From the list given below, use functions to display only the numbers that are divisible by 5.
Stop the loop if a number greater than 80 is encountered.

numbers = [10, 12, 15, 20, 33, 45, 50, 60, 85, 90]
3. Write a Python program that takes a word from the user and reverse it.
