What are the characteristics of sequence unpacking and its convenient assignment in python

In view of the characteristics and convenient assignment of sequence unpacking in python, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Characteristics of sequence unpacking in python

1. Multivariable assignment

Assign values in the form of tuples, with multiple variables separated by commas, corresponding to multiple values separated by commas. Examples are as follows:

XMagol 333555 # assign XBI y to each value.

two。 Exchange assignment

In other programming languages, we often exchange two values with the help of third-party variables, but in python we provide a very convenient method of variable exchange assignment. Examples are as follows:

X # swap the values of x and y

3. Other convenient ways to assign values

Continuous assignment

A=b=c=666

Incremental writing method in the application of mathematical operation

J=j+1 corresponds to an incremental assignment.

J=j-1 corresponds to jmurf 1.

J=j*2 corresponds to jackers 2

J=j/2 corresponds to jAction2

4. Summary and emphasis

1. The number of left and right sides of the equal sign must be equal.

2. Continuous assignment a=b=c=6

3. Exchange for x ~ (th) ~

4. the abbreviation of basic operation.

This is the answer to the question about the characteristics of sequence unpacking in python and its convenient assignment. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
