# The following line would cause an IndexError if uncommented:
# print(values[2])  # This would cause an IndexError

# The following line would cause a TypeError if uncommented:
# values[1] = 30    # This would cause a TypeError as tuples are immutable

# The following line would print the modified tuple if the previous line worked:
# print(values)

# This script demonstrates how to define and call functions

# This script demonstrates the use of return statements in functions

# Define a function 'square' that returns the square of a number
