Day 2: Writing and Appending to Files

Introduction

Writing to Files:

with open('example.txt', 'w') as file:
    file.write("Hello, World!\n")
    file.write("This is a test file.\n")

Appending to Files:

with open('example.txt', 'a') as file:
    file.write("This line will be appended.\n")

Handling Exceptions:

try:
    with open('nonexistent.txt', 'r') as file:
        content = file.read()
except FileNotFoundError:
    print("File not found. Please check the file name.")

Challenges

Challenge 1: Write to a File

Write a script that asks the user for input and writes it to a file.

Challenge 2: Append to a File

Modify the previous script to append user input to the file instead of overwriting it.

Challenge 3: Error Handling

Enhance your script with exception handling to manage scenarios where the file might not exist or cannot be opened.
