When tuple is preferred over list

Question

As tuples are immutable, they are inflexible. So, can you show some examples, where tuples are desirable

Answer 1

Tuples are faster than. If you're defining a constant set of values and all need to do with it is iterate through it, then use of a tuple is better instead of a list.

It makes the code safer if the data “write-protect” that does not need to be changed. Using a tuple instead of a list is like having an implied assert statement that this data is constant, and that special thought (and a specific function) is required to override that. Like geometrical coordinates, which always have three value.

Answer 2

You can create a list of days the week. days_week=(monday, ..., ...)
