Instances of this class have attributes filename, lineno, offset and text for easier access to the details. str() of the exception instance returns only the message. exception IndentationError¶ Base class for syntax errors related to incorrect indentation. In this case, you're trying to run the mountain.py file, and trying to call the toolkit.interface.py module, which are in separate directories. this content

exception Warning¶ Base class for warning categories. This particular side effect is rarely a problem, but some side effects can be more troublesome. By top level I mean lines that will be executed during compilation as opposed to the contents of functions (eg. If Six Is Easy, Is Ten So Hard? https://docs.python.org/2/library/exceptions.html

Python Exceptions List

Interviewee offered code samples from current employer -- should I accept? 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 All user-defined exceptions should also be derived from this class. exception RuntimeError¶ Raised when an error is detected that doesn't fall in any of the other categories.

  1. As you said, you could define your own import_safe function: def import_safe(module): try: return __import__(module) except ImportError as error: print "You don't have module {0} installed".format(error.message[16:]) Then you can use the
  2. Floating point exception handling is not standardized, so floats are not checked.
  3. Not the answer you're looking for?
  4. It doesn't rely on any special "tricks" and because of that should be pretty robust.
  5. Corresponds to errno EEXIST.
  6. Base Classes¶ The exception classes are defined in a hierarchy, described in the standard library documentation.
  7. Easiest way I found to do this was to navigate to my project folder in Windows explorer and searching for *.pyc, then selecting all (Ctrl+A) and deleting them (Ctrl+X).
  8. This can be while importing a module, invoking exec, or calling eval().

But, I can't remove the dependency to physics in entity, because class Ent needs to call it to update its position. Are there any historically significant examples? more hot questions question feed lang-py about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation Python Valueerror Example import sys print 'Regular integer: (maxint=%s)' % sys.maxint try: i = sys.maxint * 3 print 'No overflow for ', type(i), 'i =', i except OverflowError, err: print 'Overflowed at ', i,

It is raised when the interpreter detects that the maximum recursion depth (see sys.getrecursionlimit()) is exceeded. If that doesn't work, enclosing each import statement in a try block is the next best solution and not un-Pythonic at all. Since sys.path usually contains . (the current directory), that's probably what you meant by being in the source directory. weblink New in version 1.5.2.

Built-in Types Next topic 6. Python Exception Class Methods exception NameError¶ Raised when a local or global name is not found. Instances of this class have attributes filename, lineno, offset and text for easier access to the details. str() of the exception instance returns only the message. Exception¶ Base class for exceptions that do not result in quitting the running application.

Python Custom Exception

Or would it be possible to define something like safe_import some_module that would behave like I want? 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), Python Exceptions List Changed in version 3.4: The filename attribute is now the original file name passed to the function, instead of the name encoded to or decoded from the filesystem encoding. Python Filenotfounderror So I would like to distinguish the different causes for an ImportError (e.g.

It is a subclass of ValueError. UnicodeError has attributes that describe the encoding or decoding error. news EDIT (2015.01.17): I did not mention we use a custom launcher dissected here. Join them; it only takes a minute: Sign up Error handling when importing modules up vote 14 down vote favorite 2 This probably has an obvious answer, but I'm a beginner. The associated value is a string giving details about the type mismatch. Python Exception Message

The default traceback display code shows these chained exceptions in addition to the traceback for the exception itself. Changed in version 3.3: EnvironmentError, IOError, WindowsError, socket.error, select.error and mmap.error have been merged into OSError, and the constructor may return a subclass. You can use a global try..except block in the entry point of your script. have a peek at these guys A call to sys.exit() is translated into an exception so that clean-up handlers (finally clauses of try statements) can be executed, and so that a debugger can execute
