This module never needs to be imported explicitly: the exceptions are provided in the built-in namespace as well as the exceptions module. For class exceptions, in a try statement with unhandled exception type unsupportedencodingexception an except clause that mentions a particular class, that clause also handles any exception classes java checked exception derived from that class (but not exception classes from which it is derived). Two exception classes that are not related via subclassing are never equivalent, even if http://stackoverflow.com/questions/5162587/unhandled-exception-type-error they have the same name. The built-in exceptions listed below can be generated by the interpreter or built-in functions. Except where mentioned, they have an "associated value" indicating the detailed cause of the error. This may be a string or a tuple containing several items of information (e.g., an error code and a string explaining https://docs.python.org/2/library/exceptions.html the code). The associated value is the second argument to the raise statement. If the exception class is derived from the standard root class BaseException, the associated value is present as the exception instance's args attribute. User code can raise built-in exceptions. This can be used to test an exception handler or to report an error condition "just like" the situation in which the interpreter raises the same exception; but beware that there is nothing to prevent user code from raising an inappropriate error. The built-in exception classes can be subclassed to define new exceptions; programmers are encouraged to derive new exceptions from the Exception class or one of its subclasses, and not from BaseException. More information on defining exceptions is available in the Python Tutorial under User-defined Exceptions. The following exceptions are only used as base classes for other exceptions. exception BaseException¶ The base class for all built-in exceptions. It is not meant to be directly

Syntax new TypeError([message[, fileName[, lineNumber]]]) Parameters message Optional. Human-readable description of the error fileName Optional. The name of the file containing the unhandled exception type code that caused the exception lineNumber Optional. The line number of the code that caused the exception Description A TypeError is thrown when an operand or argument passed to a function is incompatible with the type expected by that operator or function. Properties TypeError.prototype Allows the addition of properties to a TypeError object. Methods The global TypeError contains no methods of its own, however, it does inherit some methods through the prototype chain. TypeError instances Properties TypeError.prototype.constructor Specifies the function that created an instance's prototype. TypeError.prototype.message Error message. Although ECMA-262 specifies that TypeError should provide its own message property, in SpiderMonkey, it inherits Error.prototype.message. TypeError.prototype.name Error name. Inherited from Error. TypeError.prototype.fileName Path to file that raised this error. Inherited from Error. TypeError.prototype.lineNumber Line number in file that raised this error. Inherited from Error. TypeError.prototype.columnNumber Column number in line that raised this error. Inherited from Error. TypeError.prototype.stack Stack trace. Inherited from Error. Methods Although the TypeError prototype object does not contain any methods of its own, TypeError instances do inherit some methods through the prototype chain. Examples Catching a TypeError
Exceptions with Improved Type Checking This page covers the following topics: Handling More Than One Type of Exception Rethrowing Exceptions with More Inclusive Type Checking Handling More Than One Type of Exception In Java SE 7 and later, a single catch block can handle more than one type of exception. This feature can reduce code duplication and lessen the temptation to catch an overly broad exception. Consider the following example, which contains duplicate code in each of the catch blocks: catch (IOException ex) { logger.log(ex); throw ex; catch (SQLException ex) { logger.log(ex); throw ex; } In releases prior to Java SE 7, it is difficult to create a common method to eliminate the duplicated code because the variable ex has different types. The following example, which is valid in Java SE 7 and later, eliminates the duplicated code: catch (IOException|SQLException ex) { logger.log(ex); throw ex; } The catch clause specifies the types of exceptions that the block can handle, and each exception type is separated with a vertical bar (|). Note: If a catch block handles more than one exception type, then the catch parameter is implicitly final. In this example, the catch parameter ex is final and therefore you cannot assign any values to it within the catch block. Bytecode generated by compiling a catch block that handles multiple exception types will be smaller (and thus superior) than compiling many catch blocks that handle only one exception type each. A catch block that handles multiple exception types creates no duplication in the bytecode generated by the compiler; the bytecode has no replication of exception handlers. Rethrowing Exceptions with More Inclusive Type Checking The Java SE 7 compiler performs more precise analysis of rethrown exceptions than earlier releases of Java SE. This enables you to specify more specific exception types in the throws clause of a method declaration. Consider the following example: static class FirstException extends Exception { } static class SecondException extends Exception { } public void rethrowException(String exceptionName) throws Exception { try { if (exceptionName.equals("First")) { throw
