What are some examples of dynamic type checking in Python?

Dynamic type checking in Python allows you to check the type of a variable at runtime. For example, you can use the isinstance() function to verify if a variable is of a specific type.

Can you show me a code example?

Sure! Here's a simple example:

def check_type(value):
    if isinstance(value, int):
        return "It's an integer!"
    elif isinstance(value, str):
        return "It's a string!"
    else:
        return "Unknown type!"

You can call check_type(10) to get "It's an integer!".

What happens if I pass a list to that function?

If you pass a list, like check_type([1, 2, 3]), it will return "Unknown type!" since the function only checks for integers and strings.

Are there any drawbacks to dynamic type checking?

Yes, dynamic type checking can lead to runtime errors if types are not as expected, making debugging more challenging.
