The built-in functions contained in tuples and how to use them are as follows:
Tuple: An unmodifiable sequence, including strings, that can be created simply by using commas or parentheses to create a tuple.
(1) Conventional tuples:
(2) The tuple function takes a sequence as a parameter and converts it to a tuple. If the parameter is already a tuple, the tuple is returned unchanged.
(3) Access to elements in tuples:
(4) The necessity of tuples: they are used as keys in maps (and members of collections), while lists are not; Some built-in functions and methods return tuples, which means you have to deal with tuples, as long as you don’t try to modify them.
Daily updates, software testing knowledge! If you don’t want to experience the feeling of giving up after a few days when you can’t find information and no one answers your questions, you can often go to some technical forums and groups and communicate with others to discuss some technical problems. There are resources (interview questions, PDF files, video tutorials) in the group (785128166)
