0What file handling is and why it’s important.
File handling in Python refers to the process of creating, opening, reading, writing, and closing files using Python programs. It allows us to store data permanently on the computer’s storage (hard disk) rather than keeping it only in the computer’s temporary memory (RAM).
In simple words:
Without file handling: Data is lost as soon as the program ends.
With file handling: Data is saved and can be used later, even after the program is closed.
Why is File Handling Important?
-
Permanent Storage of Data: Stores data so it is available even after the program ends.
-
Data Sharing: Makes it easy to share data between programs or users.
-
Large Data Handling: Useful when working with big datasets that cannot fit into memory at once.
-
Reusability: Stored data can be used again without re-entering.
-
Real-Life Applications: Used in banking systems, inventory management, student records, and almost every software that saves data.
