How does if-else performance compare in Python?

How does if-else performance compare in Python?

In Python, if-else statements are generally efficient, but their performance can vary based on the number of conditions and the complexity of the expressions.

Are there any alternatives to if-else that might perform better?

Yes, alternatives like dictionary mapping or using the match statement (introduced in Python 3.10) can improve performance in certain cases.

Can you give an example of using a dictionary for conditional logic?

Sure! Instead of using if-else, you can create a dictionary where keys are conditions and values are the corresponding actions. For example:

actions = {
    'a': action_a,
    'b': action_b,
    'c': action_c
}

action = actions.get(condition, default_action)

What about performance benchmarks for these methods?

Performance benchmarks can vary, but generally, using dictionaries can be faster for a large number of conditions due to O(1) average time complexity for lookups.
