[14/08, 12:40 am] Meta AI: File Handling in Python Introduction File handling is a crucial aspect of programming in Python, allowing you to interact with files on your system. Python provides built-in functions and modules to perform various file operations, such as reading, writing, and manipulating files. Types of Files - *Text Files:* Files containing plain text, such as `.txt` files. - *Binary Files:* Files containing binary data, such as images, audio files, or executable files. File Operations - *Reading Files:* Use the `open()` function to open a file in read mode (`'r'`) and read its contents using methods like `read()`, `readline()`, or `readlines()`. - *Writing Files:* Use the `open()` function to open a file in write mode (`'w'`) and write data to it using methods like `write()` or `writelines()`. - *Appending Files:* Use the `open()` function to open a file in append mode (`'a'`) and add data to the end of the file. File Modes - *`'r'`:* Read mode (default) - *`'w'`:* Write mode (overwrites existing file) - *`'a'`:* Append mode - *`'x'`:* Create mode (fails if file already exists) - *`'b'`:* Binary mode - *`'t'`:* Text mode (default) - *`'+'`:* Update mode (reading and writing) Example Code Reading a file with open('', 'r') as file: content = () print(content) Writing to a file with open('', 'w') as file: ('Hello, World!') Appending to a file with open('', 'a') as file: ('nThis is an appended line.')
