Python Bootcamp in a Day - Python Programming for Beginners - Text File Modes

The video tutorial explains different file modes in programming, focusing on read, write, and append modes. It highlights how write mode creates a new file, erasing existing content, while append mode adds new content to the end of the file without altering existing data. The tutorial also demonstrates the practical implications of using these modes in code execution.

What happens to the existing content of a file when it is opened in append mode?

• It is duplicated.

• It is deleted.

• It remains unchanged.

• It is overwritten.

What is the result of opening a file in write mode?

• The file is locked for editing.

• A new empty file is created.

• The file is duplicated.

• The file is appended with new content.

When a file is reopened in write mode, what happens to the previous content?

• It is encrypted.

• It is preserved.

• It is moved to a backup file.

• It is erased.

How does append mode affect the length of a file when it is reopened?

• The file length is reset to zero.

• The file length increases.

• The file length remains the same.

• The file length decreases.

What is the main difference between write mode and append mode when reopening a file?

• Both modes add content to the end.

• Write mode adds content to the end, append mode starts fresh.

• Both modes start fresh.

• Write mode starts fresh, append mode adds content to the end.
