What are some examples of I/O operations in programming?

I/O operations refer to input and output processes in programming. Examples include reading from a file, writing to a database, or sending data over a network.

Can you explain how file reading works in Python?

Sure! In Python, you can read a file using the open() function, followed by the read() method. For example:

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

What about writing to a file?

To write to a file in Python, you can use the open() function with the 'w' mode. Here's an example:

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

Are there any differences between reading and writing modes?

Yes, reading mode ('r') allows you to read data from a file, while writing mode ('w') allows you to write data. Writing mode will overwrite the file if it exists.
