Solution : Without using function
Program/Source Code

Python program to swap two numbers

#using third variable
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
print("1st value ",a," 2nd value ",b)
t=a
a=b
b=t
print("1st value ",a," 2nd value ",b)

Output:

Enter 1st no 10
Enter 2nd no 20
1st value 10 2nd value 20
1st value 20 2nd value 10
>>>



Solution without using functions and without using third variable
Program/Source Code

#without using third variable
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
print("1st value ",a," 2nd value ",b)
a=a+b
b=a-b
a=a-b
print("1st value ",a," 2nd value ",b)

Output:

Enter 1st no 10
Enter 2nd no 20
1st value 10 2nd value 20
1st value 20 2nd value 10
>>>



Solution without using functions and using only a single line
Program/Source Code

#using only a single line
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
print("1st value ",a," 2nd value ",b)
a,b=b,a
print("1st value ",a," 2nd value ",b)

Output:

Enter 1st no 100
Enter 2nd no 200
1st value 100 2nd value 200
1st value 200 2nd value 100
>>>



Solution using functions without passing arguments
Program/Source Code

#function definition
def swap():
    a=int(input("Enter 1st no "))
    b=int(input("Enter 2nd no "))
    print("1st value ",a," 2nd value ",b)
    a,b=b,a
    print("1st value ",a," 2nd value ",b)

#function calling
swap()

Output:

Enter 1st no 3
Enter 2nd no 6
1st value 3 2nd value 6
1st value 6 2nd value 3
>>>



Solution using functions and by passing arguments
Program/Source Code

#function definition
def swap(a,b):
    print("1st value ",a," 2nd value ",b)
    a,b=b,a
    print("1st value ",a," 2nd value ",b)

#function calling
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
swap(a,b)

Output:

Enter 1st no 25
Enter 2nd no 96
1st value 25 2nd value 96
1st value 96 2nd value 25
>>>



Solution using functions and by passing arguments and returning multiple values
Program/Source Code

#function definition
def swap(p,q):
    p,q=q,p
    return p,q

#function calling
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
print("Before swap 1st value ",a," 2nd value ",b)
a,b=swap(a,b)
print("After swap 1st value ",a," 2nd value ",b)

Output:

Enter 1st no 100
Enter 2nd no 200
Before swap 1st value 100 2nd value 200
After swap 1st value 200 2nd value 100
