Open a file in Python

Any online application must have file management capabilities.

To generate, read, update, and delete files, Python includes a number of functions.

File handling

The open() function is crucial for working with files in Python.

File name and mode are the two parameters that the open() function accepts.


A file can be opened in four different ways (modes):

"r" - to read; Default: Opens a read file and returns an error if the file is missing.

"a" - Append - Opens a file for appending and, if necessary, generates a new copy of the file.

"w" - opens a writable file and, if the file doesn't already exist, creates it.

"x" - Creates the provided file and returns an error if it already exists.


You can also define how the file should be handled.

"t" -  Text - Default. The text.

"b" -  Binary - Binary Mode.

Syntax

f = open("fichier.txt", "rt")
