Can you explain switch case in Python?

Python doesn't have a built-in switch case statement like some other languages. However, you can achieve similar functionality using dictionaries or if-elif-else statements.

How would I use a dictionary to mimic switch case?

You can create a dictionary where keys are the cases and values are the actions. For example:

def switch_case(case):
    return {
        'case1': 'Action for case 1',
        'case2': 'Action for case 2',
    }.get(case, 'Default action')

What about using if-elif-else?

You can use if-elif-else like this:

if case == 'case1':
    return 'Action for case 1'
elif case == 'case2':
    return 'Action for case 2'
else:
    return 'Default action'

Are there any performance differences between the two methods?

Generally, using a dictionary can be faster for many cases, especially with a large number of cases, as it provides O(1) average time complexity for lookups.
