What are some common exceptions in Python?

Some common exceptions in Python include ValueError, TypeError, KeyError, and IndexError. Would you like to know how to handle them?

Yes, how do I handle a ValueError?

You can handle a ValueError using a try-except block. For example:

try:
    value = int(input('Enter a number: '))
except ValueError:
    print('That was not a valid number!')

What about a KeyError?

For a KeyError, you can also use a try-except block. Here's an example:

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

Can you give me a summary of all these exceptions?

Sure! ValueError occurs when a function receives an argument of the right type but inappropriate value. KeyError happens when a dictionary key is not found. TypeError is raised when an operation or function is applied to an object of inappropriate type, and IndexError occurs when trying to access an index that is out of range.
