How do you swap values between two variables in a single line Python?

In short, the expression: “ a, b = b, a”, first right gets assigned to first left and second right get assigned to second left at the same time therefore swap values of a and b.

How do you switch variables in one line?

C program to swap two variables in single line

1. #include
2. void main()
3. {
4. int a = 5;
5. int b = 10;
6. (a ^= b), (b ^= a), (a ^= b);
7. printf(“Swapped values of a and b are \%d \%d”,a, b);
8. }

Which is the correct way to swap value of two variables?

The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ. For example, XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111 and XOR of 7 (0111) and 5 (0101) is (0010).

How do you swap multiple variables in Java?

Java Program to Swap two Variables

1. Assign x to a temp variable : temp = x.
2. Assign y to x : x = y.
3. Assign temp to y : y = temp.

How do I change values in two variables in CPP?

The function std::swap() is a built-in function in the C++ Standard Template Library (STL) which swaps the value of two variables.

1. Syntax:
2. Parameters: The function accepts two mandatory parameters a and b which are to be swapped.

How do you write a swap function in Python?

To swap values of variables, write as follows:

1. a = 1 b = 2 a, b = b, a print(‘a = ‘, a) print(‘b = ‘, b) # a = 2 # b = 1.
2. a, b = 100, 200 print(‘a = ‘, a) print(‘b = ‘, b) # a = 100 # b = 200.

How can I swap two values without using third variable in C++?

C++ Program to swap two numbers without third variable

1. #include
2. using namespace std;
3. int main()
4. {
5. int a=5, b=10;
6. cout<<“Before swap a= “<
7. a=a*b; //a=50 (5*10)
8. b=a/b; //b=5 (50/10)

How do you swap two values in an array C++?

Example 2: Using std::swap() to swap elements The built-in swap() function can swap two values in an array . template void swap (T& a, T& b); The swap() function takes two arguments of any data type, i.e., the two values that need to be swapped.

How do you write a swap function in CPP?

Here is the syntax of swap() in C++ language, void swap(int variable_name1, int variable_name2); If we assign the values to variables or pass user-defined values, it will swap the values of variables but the value of variables will remain same at the actual place.
