Python tuple (tuple)

Tuples in Python are similar to lists, except that elements in tuples cannot be modified (so tuples are also called read-only lists), and tuples use parentheses while lists use square brackets.

1. When there is only one element in a tuple, you need to add a comma after the element to disambiguate.

2. The element value in the tuple is not allowed to be modified, but the tuple can be connected and combined.

3. Elements in a tuple are not allowed to be deleted, but you can use the de statement to delete the entire tuple

4. + and * can be used between tuples, that is, tuples are allowed to be combined and copied repeatedly, and a new tuple is generated after the operation.
