CONCEPT:
To read or write a file, first we need to open it.
Python provides a function open(), which returns a file object with which we can read and write in the file. But in the end, we need to close the file using close() function call.
If we don’t call the close() function, the file will remain open, and its object will be consuming the memory of our process.
Therefore it is a standard practice to close an open file as a closed file reduces the risk of being unwarrantedly modified or read.
The “with statement” creates an execution block and the object created in the with statement will be destroyed when the execution block ends.

Advantages of calling open() using “with statement”:
- Files gets closed automatically.
- Fewer chances of bugs due to coding error
- Open multiple files in a single “with statement”

Advantage of Using With Clause While Opening a File: The File Closed Automatically
The with statement in Python is used to wrap the execution of a block of code with methods defined by a context manager. When it comes to file handling, the with statement is particularly useful as it ensures that the file is automatically closed after the block of code is executed. This has several advantages:
1. Automatic File Closure:
When a file is opened using the with statement, the file object is automatically closed at the end of the block. This eliminates the need for explicit calls to the file's close() method, ensuring that the file is always closed properly. By automatically closing the file, potential issues such as resource leaks or data corruption are avoided.
2. Exception Handling:
The with statement also provides a built-in exception handling mechanism. If an exception occurs within the block of code, the file is still closed before the exception is propagated further. This is crucial for preventing file-related errors from causing the program to terminate abruptly and potentially leaving the file in an inconsistent state.
3. Readability and Simplicity:
Using the with statement makes the code more readable and concise. The intention of opening and closing a file is clearly expressed in a single block, making the code easier to understand. It eliminates the need for additional try-finally blocks or explicit checks to ensure the file is closed.
4. Efficient Resource Management:
By automatically closing the file, the with statement ensures efficient resource management. It guarantees that system resources, such as file handles, are released promptly when they are no longer needed. This is especially important when dealing with a large number of files or when working with limited resources.
In summary, the with clause while opening a file provides the advantage of automatically closing the file after the block of code is executed. This ensures proper resource management, simplifies the code, and prevents potential errors or data corruption. By using the with statement, the file handling process becomes more efficient and less error-prone.
