# What is the difference between opening a file for '''writing''' data as opposed to opening a file for '''appending''' data? What can be the consequence if you don't understand the difference between writing and appending data?

# Write a Python command to open the file '''customer-data.txt''' for writing data.

# Briefly explain the process of using a loop to write a list as separate lines within an open file.

# What is the purpose of '''handling''' exception errors?

# Write a Python script to prompt a user for the name of the file to open. Use exception error handling to provide an error message that the specific file name (display that exact name) does not exist; otherwise, open the file for reading and display the entire contents of the file (line-by-line).
