introduction

Here I’ll put some introduction to File

Opening a File:

The first thing to do when working with files is to open a file, which something you normally do when you want to read the content of a file.

Python has a open() function built into You can open a file using the open() function. The syntax is:

Open file and return a corresponding file object. If the file cannot be opened, an OSError is raised

syntax:

open(file)

file is a path-like object giving the pathname (absolute or relative to the current working directory) of the file to be opened.

Example

file = open("names.txt")

If the file is not found, FileNotFoundError: exception is raised with - No such file or directory: ‘welcome.txt’ message

Closing a file

You hould always close a file after opening it, either for read, write or modification.
