Day 13 of #100DaysOfCode in Python: Mastering File Handling

Welcome to Day 13 of the #100DaysOfCode challenge! Today, we’re exploring the world of file handling in Python. File handling is a crucial skill as it enables your programs to interact with files stored on your computer, allowing for data storage, retrieval, and manipulation.

Understanding File Handling in Python

File handling is the process of reading data from and writing data to a file. Python has a range of built-in functions that make it easy to work with files. File handling enables you to perform operations like creating, reading, writing, and modifying files.

Key Operations in File Handling

• Opening a File: Before performing any operations on a file, it needs to be opened using Python’s built-in open()function.
• Reading a File: Python has several methods like read(), readline(), or readlines() to read content from a file.
• Writing to a File: You can write to a file using methods like write() or writelines().
• Closing a File: After all operations are done, it is a good practice to close the file using the close() method.
