File handling in Python is an essential part of data analysis as it allows users to store, retrieve, and manipulate data from text files efficiently. Python provides built-in functions that make file operations simple and flexible. The basic workflow of file handling includes opening a file, performing operations such as reading or writing, and then closing the file. This is typically done using the open() function, which takes the file name and mode as arguments. File modes determine how a file is accessed. The most commonly used modes include ‘r’, ‘w’, ‘a’, and ‘x’. The ‘r’ mode stands for read mode and is used to open a file for reading only. If the file does not exist, it raises an error. The ‘w’ mode stands for write mode and is used to create a new file or overwrite an existing file. If the file already exists, its content is erased. The ‘a’ mode represents append mode, which allows data to be added at the end of an existing file without modifying its original content. The ‘x’ mode is used for exclusive creation of a file and raises an error if the file already exists. In addition to
