Python Tutorial - 13. Reading/Writing Files

description
In this python tutorial, we will clarify about reading/ writing files, how to work with a file, how to open, create and close a file, use of “functions”, “modules” and “flags”. Code used in this tutorial: https://github.com/codebasics/py/blob/master/Basics/13_read_write_file.py Exercise: https://github.com/codebasics/py/blob/master/Basics/Exercise/13_read_write_files/read_write_file_exercise.md Topics that are covered in this Python Video: 0:00 Overview 0:32 Open() function 1:35 write() function 1:51 close() function 2:54 append mode in a file 4:06 read from a file 5:10 read mode in a file 5:35 read() function 7:19 Split() function 11:50 File opening modes 13:23 with statement 14:16 close Flag in file Do you want to learn technology from me?
