How can I handle KeyErrors in Python?

You can handle KeyErrors in Python using try-except blocks or by using the .get() method on dictionaries.

Can you show me an example of using try-except?

Sure! Here's a simple example:

my_dict = {'a': 1, 'b': 2}
try:
    print(my_dict['c'])
except KeyError:
    print('Key not found!')

What about using the .get() method?

Using the .get() method is straightforward. It returns None if the key doesn't exist:

value = my_dict.get('c')
if value is None:
    print('Key not found!')

Are there any other ways to avoid KeyErrors?

Yes, you can also check if a key exists using the 'in' keyword before accessing it:

if 'c' in my_dict:
    print(my_dict['c'])
else:
    print('Key not found!')
