This article mainly introduces the python how to exchange the value of the two variables of the relevant knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe you will have something to gain after reading this python how to exchange the value of the two variables, let's take a look.

The operating environment of this tutorial: windows7 system, Python 3.9.1 Dell G3 computer.

1. It is unique and the easiest way in python.

A _

2. Introduce the third variable, which can be regarded as two bottles an and b filled with milk. If I want to change milk in these two bottles, I need an empty bottle temp. First, pour the milk from bottle an into the empty bottle temp. At this point, bottle an is empty, and the milk in bottle b can be poured into a, and then the milk from temp is poured into b for exchange.

Temp=aa=bb=temp

3. Implement using XOR operation (not available when a _ domain b is equal)

Known a, b > > a = 2 > > b = 5 > > a = a ^ b > > A7 > b = a ^ b > > b2 > a = a ^ b > > A5 > >

4. Adopt special operation methods, such as addition and subtraction.
