# Traditional approach
file = open("data.txt", "r")
try:
    data = file.read()
    # Process the data
finally:
    file.close()

# Context manager
with open("data.txt", "r") as file:
    data = file.read()
    # Process the data

How can context managers improve the efficiency of my code?

Context managers are an excellent tool for managing resources efficiently and ensuring proper cleanup. They allow you to allocate and release resources automatically by defining a setup and teardown code block. One of the most common use cases of context managers is working with files, where they handle opening and closing operations seamlessly.
