How can I avoid key errors in Python dictionaries?

How can I avoid key errors in Python dictionaries?

You can avoid key errors by using the get() method or by checking if the key exists with in.

Can you show me an example using the get() method?

Sure! Instead of my_dict[key], use my_dict.get(key, default_value). This returns default_value if the key doesn't exist.

What if I want to raise an error instead of using a default value?

You can use a simple if statement to check for the key first, like this: if key in my_dict: ....

Thanks! Are there any other methods to handle this?

Yes, you can also use collections.defaultdict to provide a default value for missing keys automatically.
