Different Methods in Python for Swapping Two Numbers without using third variable

In this tutorial, we will discuss different methods used for swapping two variables (n1 and n2) without using a third variable in Python programs.

Example:

Method 1: By using inbuilt method

The inbuilt method can work with any data type values such as string, float, it. This method is very easy to use.

Example:

Output:

Variables Value Before Swapping: 
Value of P:  JavaTpoint
Value of Q:  Tutorial
Variables Value After Swapping: 
Value of P:  Tutorial
Value of Q:  JavaTpoint

Method 2: By using Bitwise XOR operator

The Bitwise XOR method only works with integers, and it works faster as it uses bit operation that is for same value result = 0 and for different value result = 1.

Example:

Output:

Variables Value Before Swapping: 
Value of P:  5
Value of Q:  10
Variables Value After Swapping: 
Value of P:  10
Value of Q:  5

Method 3: By using Addition and Subtraction Operators

This method can be used only for numerical values.

Example:

Output:

Variables Value Before Swapping: 
Value of P:  112
Value of Q:  211
Variables Value After Swapping: 
Value of P:  112
Value of Q:  211

Method 4: By using Multiplication and Division Operators

This method can be only used for numerical value except 0.

Example:

Output:

Variables Value Before Swapping: 
Value of P:  11.2
Value of Q:  21.1
Variables Value After Swapping: 
Value of P:  21.1
Value of Q:  11.2

Method 5: By using both Bitwise operators and Arithmetic operators

In this method, we will use both bitwise operators and arithmetic operators. This method only works with integers and not with float types.

Example:

Output:

Variables Value Before Swapping: 
Value of P:  112
Value of Q:  211
Variables Value After Swapping: 
Value of P:  211
Value of Q:  112

Conclusion

In this tutorial, we have discussed different methods used for swapping values of two variables without using the third variable.
