Built-in Exceptions — Python 3.14.7 documentation
If an object is meant to support a given operation but has not yet provided an implementation, NotImplementedError is the proper exception to raise. Passing arguments of the wrong type (e.g. passing a list when an int is expected) should result in a TypeError, but passing arguments with the wrong value (e.g.

Raised when a system-related operation (like file I/O, opening files, or interacting with the OS) fails. In Python 3: IOError is just an alias for OSError (they are the same). FileNotFoundError is a subclass of OSError, specifically raised when a file or directory does not exist. Example: This example attempts to open a missing file, which triggers FileNotFoundError (a subclass of OSError). ... try: open("non_existent_file.txt") # File does not exist except FileNotFoundError as e: # More specific print("FileNotFoundError caught:", e) except OSError as e: # General OS-related error print("OSError caught:", e)

May 29, 2026 - An exception, on the other hand, is a condition that interrupts the program's normal flow but can be handled within the program using try-except blocks, allowing the program to continue executing. Yes, Python allows you to catch multiple exceptions in a single try-except block by using a tuple of exception types. For example: except (TypeError, ValueError):. This will handle either a TypeError or a ValueError in the same block.

October 21, 2021 - For example, they occur when we attempt to open (read) a file that does not exist (FileNotFoundError), divide an integer by zero (ZeroDivisionError), or import a module that does not exist (ImportError). Python generates an exception object if these types of runtime issues occur.

March 18, 2026 - In the Python docs, you can see that there are a couple of built-in exceptions that you could raise in such a situation, for example: ... Raised when a file or directory is requested but doesn’t exist. Corresponds to errno ENOENT. (Source) You want to handle the situation when Python can’t find the requested file. To catch this type of exception and print it to screen, you could use the following code: ... try: with open("file.log") as file: read_data = file.read() except FileNotFoundError as fnf_error: print(fnf_error)

Python Exception Handling - GeeksforGeeks
The bare except catches it, but this can make debugging harder since the actual error type is hidden. Use bare except only as a net. We raise an exception using the raise keyword followed by an instance of the exception class that we want to trigger. We can choose from built-in exceptions or define our own custom exceptions by inheriting from Python's built-in Exception class. ... Example: This code raises a ValueError if an invalid age is given.

January 29, 2026 - In this example, the div() function attempts to perform division on the arguments a and b. However, the first argument passed to the function is a string “10”, and the second argument is an integer 2. Attempting to divide a string by an integer results in a TypeError in Python because string division with an integer is not supported. The ValueError exception occurs when a built-in operation or function expects an argument of correct data type but receives an inappropriate or invalid value for that operation.

19.4. Standard Exceptions — Foundations of Python Programming
Most of the standard exceptions built into Python are listed below. They are organized into related groups based on the types of issues they deal with. All exceptions are objects. The classes that define the objects are organized in a hierarchy, which is shown below. This is important because the parent class of a set of related exceptions will catch all exception messages for itself and its child exceptions. For example, an ArithmeticError exception will catch itself and all FloatingPointError, OverflowError, and ZeroDivisionError exceptions.

October 29, 2022 - If you run into this Python exception, the solution is to search for syntax errors in your code and fix them. This exception indicates that you tried to perform an operation using the wrong data type. As the following example demonstrates, you cannot “add” a number and a string: value = 5 name = 'John' print(value + name) # TypeError: unsupported operand type(s) for +: 'int' and 'str' This exception often appears when you try to perform an operation with a None value – which is a type that accepts no operations.

How to use Python exception types | LabEx
At LabEx, we emphasize the importance of understanding and effectively using exception handling to write more resilient Python applications. Python provides several mechanisms to handle exceptions effectively: try: ## Code that might raise an exception result = risky_operation() except ExceptionType: ## Handle specific exception handle_error() def process_data(data): try: ## Multiple potential exception scenarios value = int(data) result = 100 / value except ValueError: print("Invalid data type") except ZeroDivisionError: print("Cannot divide by zero")

Python Try Except
The finally block lets you execute code, regardless of the result of the try- and except blocks. ... When an error occurs, or exception as we call it, Python will normally stop and generate an error message. These exceptions can be handled using the try statement: The try block will generate an exception, because x is not defined: try: print(x) except: print("An exception occurred") Try it Yourself » · Since the try block raises an error, the except block will be executed. Without the try block, the program will crash and raise an error:
