Context Managers in Python

 Context Managers in Python

Context managers are a way to manage resources, such as files or network connections, in a way that ensures they are properly closed or cleaned up when no longer needed. Here's an example of using a context manager with a file:

python

with open('myfile.txt', 'r') as f:

    contents = f.read()

    print(contents)

In this example, we use the open function to open a file called myfile.txt in read mode. We then use the with statement to create a context manager that will automatically close the file when the block is finished executing.

Inside the block, we read the contents of the file using the read method and print them to the console.
