Take another look at this code: try: params = read_params(param_file) grid = read_grid(grid_file) entropy = lee_entropy(params, grid) write_entropy(entropy_file, entropy) except IOError as err: report_error_and_exit('Cannot read/write' + err.filename) except ArithmeticError as err: def throws_global_name_error(): print unknown_global_name def throws_unbound_local(): local_val = local_val + 1 print local_val try: throws_global_name_error() except NameError, err: print 'Global name error:', err try: throws_unbound_local() except UnboundLocalError, err: print 'Local name There are many places in our program where an error might occur. Exception hierarchy Previous topic 5. check over here
The Python Software Foundation is a non-profit corporation. Long integers allocate more space as values grow, so they end up raising MemoryError. This is a subclass of SyntaxError. Some built-in exceptions (like IOError) expect a certain number of arguments and assign a special meaning to the elements of this tuple, while others are usually called only with a https://docs.python.org/2/library/exceptions.html
exception UnboundLocalError¶ Raised when a reference is made to a local variable in a function or method, but no value has been bound to that variable. Corresponds to errno EEXIST. It is not meant to be directly inherited by user-defined classes (for that, use Exception). The associated value is a string giving details about the type mismatch.
This may be a string or a tuple containing several items of information (e.g., an error code and a string explaining the code). Raised when a VMS-specific error occurs. exception ArithmeticError¶ The base class for those built-in exceptions that are raised for various arithmetic errors: OverflowError, ZeroDivisionError, FloatingPointError. Python Exception Message Join them; it only takes a minute: Sign up Indentation not working properly in emacs for python up vote 9 down vote favorite I am using emacs-for-python provided by gabrielelanaro at
If anyone could help me figure this out, I would be greatly appreciative. 5 commentsshareall 5 commentssorted by: besttopnewcontroversialoldrandomq&alive (beta)[–]krekling 2 points3 points4 points 2 years ago(3 children)This is a known bug, and has BaseException¶ Base class for all exceptions. object¶ The object the codec was attempting to encode or decode. click to read more If the value is an integer, it specifies the system exit status (passed to C's exit() function); if it is None, the exit status is zero; if it has
Suggestion error with Coveo search box Was the Oceanic flight 815 pilot the only one attacked by the monster? Python Exception Class Methods IndexError Raised when a sequence subscript is out of range. ValueError¶ A ValueError is used when a function receives a value that has the right type but an invalid value. New in version 3.5: Previously, a plain RuntimeError was raised.
exception ArithmeticError¶ Bases: exceptions.StandardError Base class for arithmetic errors. https://www.reddit.com/r/emacs/comments/2axgse/mysterious_arithmetic_error_appears_when_i_try_to/ Then open your py file and try the TAB indent. Type Error Python You should report this to the author or maintainer of your Python interpreter. Python Custom Exception exception Warning¶ Base class for warning categories.
The associated value is usually passed as arguments to the exception class's constructor. check my blog exception IndexError¶ Raised when a sequence subscript is out of range. (Slice indices are silently truncated to fall in the allowed range; if an index is not a plain integer, So much for how exceptions work: how should they be used? This allows the exception to properly propagate up and cause the interpreter to exit. Corresponds to errno ESRCH. this content In a try statement with an except clause that mentions a particular class, that clause also handles any exception classes derived from that class (but not exception classes from This may occur in an import statement, in an exec statement, in a call to the built-in function eval() or input(), or when reading the initial script Python Errno In most cases, these base classes are not intended to be raised directly. StandardError¶ Base class for built-in exceptions used in the standard library.
The library therefore shouldn't try to handle or report errors itself, because it has no way of knowing what the right way to do this is.

StandardError¶ Base class for built-in exceptions used in the standard library.
See the module errno, which contains names for the error codes defined by the underlying operating system. This is a subclass of NameError. Last updated on Sep 20, 2016. Python Attributeerror Object Has No Attribute FutureWarning Warning about changes to the language or library that are coming at a later time.
This is a subclass of IndentationError. Instances have an attribute code which is set to the proposed exit status or error message (defaulting to None). Please report this to the Python maintainer, along with the traceback, the Python version, and the hardware/OS platform and version. have a peek at these guys The os._exit() function can be used if it is absolutely positively necessary to exit immediately (for example, in the child process after a call to os.fork()).
An implicitly chained exception in __context__ is shown only if __cause__ is None and __suppress_context__ is false. exception WindowsError¶ Only available on Windows. 5.2.1. exception ReferenceError¶ Bases: exceptions.StandardError Weak ref proxy used after referent went away. exception ImportWarning¶ Base class for warnings about probable mistakes in module imports.
exception BlockingIOError¶ Raised when an operation would block on an object (e.g. 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 It should instead just raise an exception, and let its caller figure out how best to handle it. For backwards compatibility, if three arguments are passed, the args attribute contains only a 2-tuple of the first two constructor arguments.
The exceptions are defined in the module exceptions. StopIteration: Raised by an iterator's next() method to signal that there are no further values. This is a subclass of SyntaxError. Changed in version 3.5: Python now retries system calls when a syscall is interrupted by a signal, except if the signal handler raises an exception (see PEP 475 for the rationale),
UnicodeDecodeError Raised when a Unicode-related encoding or decoding error occurs. python-indent-line: Arithmetic error *Backtrace* buffer: Debugger entered--Lisp error: (arith-error) python-indent-calculate-levels() python-indent-line() python-indent-line-function() indent-according-to-mode() newline-and-indent() call-interactively(newline-and-indent nil nil) command-execute(newline-and-indent) The patch below resolves the problem by ensuring that the function `python-indent-guess-indent-offset` does Changed in version 2.6: Changed to inherit from BaseException. The associated value is a string indicating what kind of (internal) operation ran out of memory.
