• mode="w"

• mode="x"

What does the 'a' in mode="a" stand for in Python file handling?

• Append

• Access

• Alter

• Analyze

What is the effect of opening a file in mode="w" if the file already contains data?

• The data is preserved.

• The data is appended.

• The data is completely erased.

• The data is encrypted.

What does the 'w' in mode="w" stand for in Python file handling?

• Write

• Wait

• Watch

• Wrap

What happens when you open a file in Python using the "w" mode and the file does not exist?

• The file is opened in read-only mode.

• An error is raised.
