1.Tuple type: In parentheses, separated by commas between different elements. The size of the tuple and the elements therein cannot be modified after initialization , and the tuple is faster than the modifiable list operation .

Note: If a developer defines a constant set of values and the only thing to do with it is to read continuously, this is the advantage of a tuple. 2. Built-in functions and operations:indexes, slices, loops, lengths, including similar lists, refer to the list

TP = ('Simon',"Hangzhou", 24) I= Tp.index (24)Print(i)Print(Tp[:2]) forTinchTP:Print(t)Print(LEN (TP))if "Simon" inchTP:Print('y')
