What is the method for swapping variable values in Python?

In Python, swapping variable values can be achieved by using a temporary variable. The specific steps are as follows:

# 定义两个变量
a = 10
b = 20

# 使用一个临时变量来交换两个变量的值
temp = a
a = b
b = temp

# 输出交换后的结果
print("a:", a)
print("b:", b)

By running the code above, you can see the output result is:

a: 20
b: 10

This method allows for the swapping of two variable values.
