使用 Python 在一行中交换两个变量？

我们将学习如何在一行中交换两个变量。假设以下内容为我们的输入 −

a = 10
b = 5

以下是在交换后我们的输出 −

a = 5
b = 10

使用逗号运算符在一行中交换两个变量

使用逗号运算符，你可以在一行中创建多个变量。此处考虑了同样的概念，并且变量值被交换 −

示例

Open Compiler
a = 5;
b = 10;

print("Variable1 = ",a);
print("Variable2 = ",b);

# Swap two variables in one line using comma operator
a, b = b, a

print("\nVariable1 (After Swapping) = ",a);
print("Variable2 (After Swapping) = ",b);

输出

Variable1 =  5
Variable2 =  10

Variable1 (After Swapping) =  10
Variable2 (After Swapping) =  5

使用乘法和除法运算符交换两个变量

可以使用以下运算符在 Python 中交换变量 −

示例

Open Compiler
a = 5;
b = 10;

print("Variable1 = ",a);
print("Variable2 = ",b);

# Swap two variables
a = a * b
b = a / b
a = a / b

print("\nVariable1 (After Swapping) = ",a);
print("Variable2 (After Swapping) = ",b);

输出

Variable1 =  5
Variable2 =  10

Variable1 (After Swapping) =  10.0
Variable2 (After Swapping) =  5.0

使用 XOR 交换两个变量

可以使用 XOR 运算符在 Python 中交换变量 −

示例

Open Compiler
a = 5;
b = 10;

print("Variable1 = ",a);
print("Variable2 = ",b);

# Swap two variables
a = a ^ b
b = a ^ b
a = a ^ b

print("\nVariable1 (After Swapping) = ",a);
print("Variable2 (After Swapping) = ",b);

输出

Variable1 =  5
Variable2 =  10

Variable1 (After Swapping) =  10
Variable2 (After Swapping) =  5
