How does type inference work in Python?

Can you explain how type inference works in Python?

Sure! In Python, type inference is the process where the interpreter deduces the type of a variable at runtime based on the value assigned to it.

Does that mean I don't have to declare variable types?

Exactly! Python is dynamically typed, so you don't need to declare types explicitly. The interpreter handles it for you.

What happens if I assign a different type later?

If you assign a different type to the same variable, Python will allow it, but you should be cautious as it can lead to runtime errors.

Can you give me an example of type inference in action?

Sure! For instance, if you write x = 10, Python infers x is an integer. If you later do x = 'hello', it changes to a string.
