Python Built-in Exceptions - Reference To All Types of Errors

1. Reference to Python Built-in Exceptions or Errors

Being a versatile and dynamically typed language, Python programming provides a robust error-handling mechanism through the use of built-in exceptions. These exceptions are events or errors that occur during the program execution, and due to a rich set of built-in exceptions, Python handles different scenarios efficiently. In this tutorial, we will provide you with a list of all the built-in exceptions or errors in Python programming. Moreover, we will also provide you with a code snippet that you may utilize to acquire the complete and up-to-date list of all the built-in exceptions in Python programming. Lastly, we will also share the heirarchy of the Python built-in exceptions or errors.

2. Search Ultimate Reference For Python Built-in Exceptions

The table below comprises all the built-in exceptions or errors in Python language and serves as an ultimate guide or reference to the developers. You can use the input field to search for any exception or error from the table. These built-in exptions of Python programming are listed alphabetically.

3. Dynamically Get All Python Built-in Exceptions

To programmatically retrieve a complete list of all the built-in Python exceptions or errors, we can utilize the following code.

# Get all built-in exceptions or errors
import builtins

# Get all attributes of the builtins module
all_attributes = dir(builtins)

# Filter out only the attributes that are classes and are exceptions
exceptions = [
attr
for attr in all_attributes
	if isinstance(getattr(builtins, attr), type) and issubclass(getattr(builtins, attr), BaseException)
]

# Print the list of exception names
for exception in exceptions:
	print(exception)

4. Heirarchy of Python Built-in Exceptions

The heirarchy of the built-in Python exceptions or errors shows that how the exceptions are related to each other. Further the Python built-in exceptions heirarchy dipicts different categories in which these are divided. See the Python built-in exceptions heirarchy below:
