Multiple Assignment

 Multiple Assignment

Multiple assignment in Python allows you to assign multiple values to multiple variables in a single line. It's a convenient way to initialize variables or swap their values without needing multiple lines of code. There are a few different ways to perform multiple assignments in Python:

1. Multiple Variables with Multiple Values:

   You can assign values to multiple variables in a single line by separating the variables and values with commas. The number of variables must match the number of values.

   ```python

   x, y, z = 1, 2, 3

   ```

2. Tuple Unpacking:

   You can use tuple packing and unpacking to assign multiple values to multiple variables. This is often used when returning multiple values from a function.

   ```python

   point = (4, 5)

   x, y = point

   ```

3. Swapping Variables:

   Multiple assignment is commonly used to swap the values of two variables without using a temporary variable.

   ```python

   a = 5

   b = 10

   a, b = b, a  # Swaps the values of a and b

   ```

4. Extended Unpacking (Python 3.0 and later):

   You can also use the `*` operator for extended unpacking. This allows you to capture multiple values into one variable, as well as to capture remaining values into another variable.

   ```python

   first, *rest = 1, 2, 3, 4, 5

   # first = 1

   # rest = [2, 3, 4, 5]

   ```

Multiple assignment is a useful feature in Python that can help make your code more concise and readable, especially when dealing with operations involving multiple variables.
