Python 3 - Standard Exceptions
Here is a list all the standard Exceptions available in Python −
| Sr.No. | EXCEPTION NAME & DESCRIPTION |
|---|---|
| 1 | Exception Base class for all exceptions |
| 2 | StopIteration Raised when the next() method of an iterator does not point to any object. |
| 3 | SystemExit Raised by the sys.exit() function. |
| 4 | StandardError Base class for all built-in exceptions except StopIteration and SystemExit. |
| 5 | ArithmeticError Base class for all errors that occur for numeric calculation. |
| 6 | OverflowError Raised when a calculation exceeds maximum limit for a numeric type. |
| 7 | FloatingPointError Raised when a floating point calculation fails. |
| 8 | ZeroDivisonError Raised when division or modulo by zero takes place for all numeric types. |
| 9 | AssertionError Raised in case of failure of the Assert statement. |
| 10 | AttributeError Raised in case of failure of attribute reference or assignment. |
| 11 | EOFError Raised when there is no input from either the raw_input() or input() function and the end of file is reached. |
| 12 | ImportError Raised when an import statement fails. |
| 13 | KeyboardInterrupt Raised when the user interrupts program execution, usually by pressing Ctrl+c. |
| 14 | LookupError Base class for all lookup errors. |
| 15 | IndexError Raised when an index is not found in a sequence. |
| 16 | KeyError Raised when the specified key is not found in the dictionary. |
| 17 | NameError Raised when an identifier is not found in the local or global namespace. |
| 18 | UnboundLocalError Raised when trying to access a local variable in a function or method but no value has been assigned to it. |
| 19 | EnvironmentError Base class for all exceptions that occur outside the Python environment. |
| 20 | IOError Raised when an input/ output operation fails, such as the print statement or the open() function when trying to open a file that does not exist. |
| 21 | OSError Raised for operating system-related errors. |
| 22 | SyntaxError Raised when there is an error in Python syntax. |
| 23 | IndentationError Raised when indentation is not specified properly. |
| 24 | SystemError Raised when the interpreter finds an internal problem, but when this error is encountered the Python interpreter does not exit. |
| 25 | SystemExit Raised when Python interpreter is quit by using the sys.exit() function. If not handled in the code, causes the interpreter to exit. |
| 26 | TypeError Raised when an operation or function is attempted that is invalid for the specified data type. |
| 27 | ValueError Raised when the built-in function for a data type has the valid type of arguments, but the arguments have invalid values specified. |
| 28 | RuntimeError Raised when a generated error does not fall into any category. |
| 29 | NotImplementedError Raised when an abstract method that needs to be implemented in an inherited class is not actually implemented. |
