How do I fix a KeyError in my Python dictionary?

I'm getting a KeyError when trying to access a value in my Python dictionary. What should I do?

A KeyError usually means that the key you're trying to access doesn't exist in the dictionary. Can you show me your code?

Sure! Here's my code: my_dict = {'a': 1, 'b': 2} and I'm trying to access my_dict['c'].

In this case, the key 'c' is not in my_dict, which is why you're getting the KeyError. You can check if a key exists using if 'c' in my_dict: before accessing it.

Got it! So I can use that check to avoid the error. Thanks!

Exactly! You can also use the .get() method, which returns None if the key doesn't exist, instead of raising an error.
