for example, there is data
("Alex",13), (" Bob",12), which is the element of name and age, respectively
it is hoped that such a data can be stuffed into the set as an element, so that data such as ("Alex",13) can be automatically deduplicated next time.
can also maintain a specific format after it is removed.
is to change such data into a string like "Alex:13", then
takes it out and splits the class on its own.
Fluent Python, but I can"t find it anywhere at the moment.
ask for advice. Is there any good way?
