Quick Check: Python Bytes and Bytearray

Review

1. What type of value does data[0] produce when data is a bytes object?

   bytes is a sequence of integers, so indexing returns the numeric byte value.
2. Which statement correctly describes bytearray?

   bytearray is mutable, so its items and slices can be changed after creation.
3. Which operation converts the text string 'Café' into UTF-8 bytes?

   str.encode() produces bytes using the requested text encoding.
4. What does data[1:4] produce when data is a bytes object?

   A bytes slice creates another bytes object containing the selected range.
5. When is bytearray usually the better choice than bytes?

   bytearray is designed for mutable binary data; bytes is the immutable form.
