Swap two variables in one line in using Python?

We will learn how to swap two variables in one line. Let’s say the following is our input −

a = 10
b = 5

The following is our output after swap −

a = 5
b = 10

Swap two variables in one line using comma operator

Using the comma operator, you can create multiple variables in a single line. The same concept is considered here and the variable values are swapped −

Example

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);

Output

Variable1 =  5
Variable2 =  10

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

Swap two variables using multiplication and division operator

Swapping variables in Python can be achieved using the operators −

Example

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);

Output

Variable1 =  5
Variable2 =  10

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

Swap two variables using XOR

Swapping variables in Python can be achieved using the XOR operator −

Example

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);

Output

Variable1 =  5
Variable2 =  10

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