Raspberry Pi For Beginners - 2022 Complete Course - Read, Write, and Manipulate Files with Python

This video tutorial covers file handling in Python, including creating, reading, writing, and appending files. It explains using terminal commands like 'touch' and 'nano' to create and edit files. The tutorial demonstrates reading files in Python using the 'with open' structure, which ensures safe file handling by automatically closing files. It also covers writing and appending text to files, and using the OS module to check for file existence and remove files. The tutorial provides practical examples and code snippets to illustrate these concepts.

What command is used in the terminal to create a new file?

• touch

• ls

• cat

• nano

Which Python function is used to open a file for reading?

• read()

• open()

• write()

• file()

What is the purpose of using 'with open' in Python?

• To automatically close the file after operations

• To read files faster

• To write files without errors

• To append data to files

Which mode should be used to write to a file, erasing its previous content?

• r+

• a

• w

• r

What happens if you open a file in 'w' mode and the file does not exist?

• The file is opened in read mode

• An error is raised

• The operation is ignored

• The file is created

Which mode allows you to append data to an existing file?

• w+

• a

• w

• r

What is the effect of using 'a' mode when opening a file?

• It deletes the file

• It overwrites the file

• It appends data to the file

• It reads the file

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

• path

• file

• os

• sys

How can you remove a file using Python?

• file.remove()

• os.remove()

• sys.delete()

• os.delete()

What should you do before removing a file to ensure it exists?

• Use os.remove() directly

• Use open() in read mode

• Use os.path.exists()

• Use a try-except block
