What are the best practices for using switch-case in Python?

Python doesn't have a built-in switch-case statement, but you can use dictionaries or if-elif-else chains. Would you like examples?

Yes, please provide an example using a dictionary.

Sure! You can create a dictionary where keys are cases and values are functions or results. For example:

def case_one(): return 'This is case one'

def case_two(): return 'This is case two'

switch = {
    'case1': case_one,
    'case2': case_two
}

result = switch.get('case1', lambda: 'Invalid case')()
print(result)  # Output: This is case one

What about using if-elif-else? Can you show me that?

Absolutely! Here's how you can use if-elif-else:

case = 'case1'

if case == 'case1':
    print('This is case one')
elif case == 'case2':
    print('This is case two')
else:
    print('Invalid case')

Are there any performance considerations I should be aware of?

Yes, using dictionaries can be more efficient for many cases, especially with a large number of conditions, as they provide O(1) average time complexity for lookups.
