How can you switch two variables in Python?

To switch or swap two variables in Python using a single line command is a unique feature of the language that simplifies the process significantly. Python allows for tuple unpacking, which enables you to switch two variables without the need for a temporary variable or any additional functions.

For example, if you have two variables, a and b, you can swap their values by writing:

a, b = b, a

This line creates a tuple from the values of b and a on the right side of the assignment and unpacks this tuple back into a and b on the left side.

This method enhances code readability and conciseness, making it an efficient way to swap variable values compared to approaches that rely on creating a temporary variable. Other methods, such as using a swap function or assigning different data types, do not offer the same simplicity or elegance in the context of variable swapping and might complicate the process unnecessarily. Thus, using a single line command is considered the most straightforward and Pythonic way to achieve this task.
