Then we introduce the sequence unpacking and assignment method. Sequence unpacking is a method of performing multiple assignment operations at the same time: unpack the sequence of multiple values ​​and then put them into the sequence of variables, as shown in the figure:

Let’s introduce the method of chain assignment. Chain assignment is to assign the same value to multiple variables, which is a bit like parallel assignment, as shown in the figure:

Finally, we introduce the method of incremental assignment. Incremental assignment is to express a variable and then reassign it to the variable, such as x=x 1, for example:

Notes

When unpacking the sequence, the number of variables on the left side of the assignment symbol is exactly the same as the number of elements in the sequence.

The so-called incremental assignment is for " *", "/", "%" and other standard operators are established
