What are some common errors I might encounter when using dictionaries in Python?
Some common errors include KeyError, TypeError, and ValueError. Would you like examples of each?
Yes, please provide examples of KeyError and TypeError.
A KeyError occurs when you try to access a key that doesn't exist. For example: my_dict['nonexistent_key']. A TypeError can happen if you use an incorrect type as a key, like a list: my_dict[[1, 2]] = 'value'.
How can I avoid these errors?
To avoid KeyErrors, use the get() method to access keys safely. For TypeErrors, ensure your keys are immutable types like strings or tuples.
