What is the difference between tuple unpacking and list unpacking in Python?
Tuple unpacking and list unpacking are similar in Python, but they apply to different data types. Tuples are immutable, while lists are mutable.
Can you give me an example of each?
Sure! For tuple unpacking: a, b = (1, 2)
assigns 1 to a
and 2 to b
. For list unpacking: x, y = [3, 4]
assigns 3 to x
and 4 to y
.
Are there any performance differences between them?
Generally, tuple unpacking can be slightly faster than list unpacking because tuples are immutable and have a smaller memory footprint.
When should I use tuples over lists?
Use tuples when you need a fixed collection of items that shouldn't change, and lists when you need a mutable sequence.
