What are the alternatives to switch case in Python?

Are there any alternatives to switch case statements in Python?

Yes, Python doesn't have a built-in switch case statement, but you can use if-elif-else chains, dictionaries, or match-case in Python 3.10 and later.

Can you explain how to use a dictionary as an alternative?

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

def switch_case(case):
    switch_dict = {
        'case1': 'Action 1',
        'case2': 'Action 2',
        'case3': 'Action 3'
    }
    return switch_dict.get(case, 'Default Action')

What about using if-elif-else? Can you give an example?

Absolutely! Here's a simple example:

if case == 'case1':
    action = 'Action 1'
elif case == 'case2':
    action = 'Action 2'
elif case == 'case3':
    action = 'Action 3'
else:
    action = 'Default Action'

What is the match-case statement?

The match-case statement, introduced in Python 3.10, allows for pattern matching. It's similar to switch case. Here's an example:

match case:
    case 'case1':
        action = 'Action 1'
    case 'case2':
        action = 'Action 2'
    case _:
        action = 'Default Action'
