What are some real-world examples of using switch-case in Python?

Python doesn't have a built-in switch-case statement, but we can use dictionaries or match-case in Python 3.10+. For example, you can use a dictionary to map user input to functions.

Can you show me a code example using a dictionary?

Sure! Here's a simple example:

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

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

switch = {
    '1': case_one,
    '2': case_two,
}

user_input = '1'
result = switch.get(user_input, lambda: 'Invalid case')()
print(result)  # Output: This is case one

What about using match-case in Python 3.10?

With match-case, it looks cleaner. Here's an example:

user_input = 'apple'

match user_input:
    case 'apple':
        print('This is an apple')
    case 'banana':
        print('This is a banana')
    case _:
        print('Unknown fruit')
