What are the differences between conditional expressions and switch-case in Python?

In Python, conditional expressions (also known as ternary operators) allow you to evaluate conditions in a single line. Switch-case statements, however, are not natively supported in Python, but you can achieve similar functionality using dictionaries or if-elif-else chains.

Can you give me an example of a conditional expression?

Sure! A conditional expression in Python looks like this: x = 'Yes' if condition else 'No'. It assigns 'Yes' to x if the condition is true, otherwise 'No'.

How would I implement a switch-case-like structure in Python?

You can use a dictionary to simulate switch-case behavior. For example:

switch = {
    'case1': function1,
    'case2': function2,
}
result = switch.get(value, default_function)()
``` This calls the function associated with the key 'value'.

Are there any performance differences between the two?

Yes, conditional expressions are generally faster for simple conditions, while using dictionaries for switch-case can be more efficient for multiple cases due to direct lookups.
