What is the use of the "with" statement in Python?

The "with" statement in Python is used to work with files in a more convenient way, as it automatically takes care of closing the file after you are done with it. The "with" statement creates a context in which the file is open, and when the indented code inside the "with" block is finished, the file is automatically closed.

For example:

with open("example.txt", "r") as f:
    contents = f.read()

This opens the file "example.txt" in read mode, reads the contents of the file into a string called "contents", and then closes the file.

Using the "with" statement is considered best practice in Python, as it eliminates the risk of forgetting to close the file, which can lead to resource leaks and other problems.
