In Python 3.10 and above, you can use the switch statement to do the same thing. With the switch statement, you don’t need to repeat the same statements multiple times (food==x), which makes the code cleaner than using multiple if-else statements.A switch function is a flow-control structure available in several high-level programming languages. It allows for cleaner, more readable code when dealing with multiple conditional statements. Python, notably, does not come with a built-in switch function. But don’t fret – it turns out that Python’s impressive flexibility offers clever ...The biggest introduction of Python 3.10 was the Match-Case statement.
