I am working on a Python script, and you encounter an error related to the misuse of lists and tuples. Here’s a simplified version of your code:

# Initializing a list
my_data = [10, 20, 30, 40, 50]

# Attempting to change the second element to 99
my_data[1] = 99

# Creating a tuple
my_tuple = (1, 2, 3, 4, 5)

# Attempting to append a new element to the tuple
my_tuple.append(6)

When I execute this code, I get an error. I’ve read multiple articles about lists and tuples but have been unable to find the programming issue; it would be great if someone could give a solution for this.
Explain the problem’s nature and the differences in how lists and tuples handle updates. Clarify when lists are appropriate and when tuples are preferable. Thank you very much.
