File Handling in Python

This video tutorial by Dave covers file operations in Python using the ROCKS acronym: Read, Append, Write, and Create. It explains how to read files, handle errors with try-except blocks, append data, write and overwrite files, and create and delete files. The tutorial also introduces the 'with' statement for more concise file handling. Throughout, practical examples are provided using VS Code, demonstrating how to manage text files effectively.

What does the 'R' in the ROCKS acronym stand for?

• Replace

• Read

• Reorder

• Remove

Which method is used to read the entire content of a file in Python?

What happens if you try to read a file that doesn't exist?

• A warning is issued

• The file is created

• An error is raised

• The program continues silently

What is the purpose of the 'a' mode when opening a file?

• To append data to the file

• To access the file

• To archive the file

• To analyze the file

Why is it important to close a file after operations?

• To save memory

• To delete the file

• To prevent data loss

• To lock the file

What does the 'w' mode do when opening a file?

• Writes data and encrypts the file

• Writes data and appends to existing content

• Writes data and overwrites existing content

• Writes data without overwriting

Which Python module is used to check if a file exists?

• pathlib

• file

• sys

• os

What does the 'x' mode do when opening a file?

• Executes the file

• Creates a new file

• Exits the program

• Exports the file

What is the advantage of using the 'with' keyword for file operations?

• It automatically closes the file

• It speeds up file operations

• It compresses the file

• It encrypts the file

What is the main benefit of using the 'with' statement over try-except-finally for file handling?

• It is more concise

• It is faster

• It is more secure

• It is more flexible
