Swapping of two numbers in python using a temporary variable.


number1 = input('Enter First Number: ')
number2 = input('Enter Second Number: ')

print("Value of num1 before swapping: ", num1)
print("Value of num2 before swapping: ", num2)

# swapping two numbers using temporary variable
temp = numberb1
number1 = number2
number2 = temp
print("Value of num1 after swapping: ", number1)
print("Value of num2 after swapping: ", number2)

Output


Enter First Number: 52
Enter Second Number: 25
Value of num1 before swapping:  52
Value of num2 before swapping:  25
Value of num1 after swapping:  25
Value of num2 after swapping:  52


Swapping of two numbers in python without using a temporary variable.


number_1 = input('Enter First Number: ')
number_2 = input('Enter Second Number: ')

print("Value of num1 before swapping: ", number_1)
print("Value of num2 before swapping: ", number_m2)
# swapping two numbers without using temporary variable
number_1, number_2 = number_2, number_1
print("Value of num1 after swapping: ", number_1)
print("Value of num2 after swapping: ", number_2)

Output


Enter First Number: 52
Enter Second Number: 25
Value of num1 before swapping:  52
Value of num2 before swapping:  25
Value of num1 after swapping:  25
Value of num2 after swapping:  52



Swapping of two numbers in python using bitwise XOR operator.


x = 5 # x = 0101 
y = 10 # y = 1010 
  
print ("Before swapping: ") 
print("Value of x : ", x, " and y : ", y) 
  
# Swap code 
x ^= y # x = 1111, y = 1010 
y ^= x # y = 0101, x = 1111 
x ^= y # x = 1010, y = 0101 
  
print ("After swapping: ") 
print("Value of x : ", x, " and y : ", y)

Output


Before swapping: 
Value of x :  5  and y :  10
After swapping: 
Value of x :  10  and y :  5


Swapping of two numbers in python using addition and subtraction operators.


x = 6
y = 7
  
print ("Before swapping: ") 
print("Value of x : ", x, " and y : ", y) 
  
# Swap code 
x = x + y
y = x - y 
x = x - y 
  
print ("After swapping: ") 
print("Value of x : ", x, " and y : ", y) 

Output


Before swapping: 
Value of x :  6  and y :  7
After swapping: 
Value of x :  7  and y :  6


Swapping of two numbers in python using multiplication and division operators.


x = 6
y = 7
  
print ("Before swapping: ") 
print("Value of x : ", x, " and y : ", y) 
  
# Swap code 
x = x * y   
y = x / y  
x = x / y 
  
print ("After swapping: ") 
print("Value of x : ", x, " and y : ", y) 

Output


Before swapping: 
Value of x :  6  and y :  7
After swapping: 
Value of x :  6  and y :  7



Swapping of two numbers in python using the function.


def swap_numbers(a, b):
    temp = a
    a = b
    b = temp
    
    print("After Swapping two Number: num1 = {0} and num2 = {1}".format(a, b))
 
num1 = float(input(" Please Enter the First Value : "))
num2 = float(input(" Please Enter the Second Value : "))

print("Before Swapping two Number: num1 = {0} and num2 = {1}".format(num1, num2))
swap_numbers(num1, num2)

Output


Please Enter the First Value :15
Please Enter the Second Value :25
Before Swapping two Number: num1 = 15 and num2 = 25
After Swapping two Number: num1 = 25 and num2 = 15


Type and Run the code by your self.




Conclusion.
