How do I handle files in Python 3.10?

In Python 3.10, you can handle files using the built-in open() function. You can open a file in different modes like 'r' for reading, 'w' for writing, and 'a' for appending.

Can you show me an example of reading a file?

Sure! Here's a simple example:

with open('example.txt', 'r') as file:
    content = file.read()
    print(content)

This code opens 'example.txt' in read mode and prints its content.

What about writing to a file?

To write to a file, you can use the 'w' mode. Here's an example:

with open('output.txt', 'w') as file:
    file.write('Hello, World!')

This will create 'output.txt' and write 'Hello, World!' to it.

How can I handle exceptions while working with files?

You can use a try-except block to handle exceptions. For example:

try:
    with open('example.txt', 'r') as file:
        content = file.read()
except FileNotFoundError:
    print('File not found!')

This will catch the FileNotFoundError if the file doesn't exist.
