Then we can interact with our file through the file handler. The OS returns a file handler if open is successful. Opening a file signals to the operating system to search for the file by its name and ensure that it exists. When we want to read or write a file, we must open it first. Python interacts with files loaded in the main memory through " file handlers". Once the processing is done, the data is written back to the secondary memory. Files are loaded from secondary memory to the main memory and then processed by the CPU. The data is lost when the computer is powered off. Main memory is the temporary cache memory that holds requested data for a brief interval. To work with files, we need to load them into the main memory first. Once you make changes to a file and save it, the changes are permanently written and saved in the secondary memory. Secondary memory is persistent, which means that data is not erased when a computer is powered off. Persistence and How to Load Files into the Main Memoryįiles reside in the computer's secondary memory. ![]() You can also clone this repo and run it on Replit.

Python has a well-defined methodology for opening, reading, and writing files. This increases efficiency and reduces manual effort. You can program your code to read data or instructions from a file and then write the data as well. Reading and writing files is a common operation when working with any programming language.
