Originally specified in PEP 302. New in version 2.6. This function wraps the Win32 GetVersionEx() function; see the Microsoft documentation on OSVERSIONINFOEX() for more information about these fields. CPython implementation detail: This function should be used for internal and specialized purposes only. http://caribtechsxm.com/python-error/python-error-log-mac.php
This is implemented by raising the SystemExit exception, so cleanup actions specified by finally clauses of try statements are honored, and it is possible to intercept the exit attempt The flag constants are defined in the dl and DLFCN modules. platform may be one of the following values: Constant Platform 0 (VER_PLATFORM_WIN32s) Win32s on Windows 3.1 1 (VER_PLATFORM_WIN32_WINDOWS) Windows 95/98/ME 2 (VER_PLATFORM_WIN32_NT) Windows NT/2000/XP/x64
sys.argv¶ The list of command line arguments passed to a Python script. argv is the script name (it is operating system dependent whether this is a full pathname or not). frame is the current stack frame. The Python Software Foundation is a non-profit corporation.
sys.path_hooks¶ A list of callables that take a path argument to try to create a finder for the path. sys.path_importer_cache¶ A dictionary acting as a cache for finder objects. PARENT: Signaling child Note that the child does not print the message embedded in not_called(). When updated destribution or deb package, please fix here.

Otherwise a TypeError will be raised. getsizeof() calls the object's __sizeof__ method and adds an additional garbage collector overhead if the object is managed by the garbage collector.

This should be done with care, because a too-high limit can lead to a crash. See section 184.108.40.206.2 of the C99 standard for an explanation of the possible values and their meanings. History #1 Updated by Travis Rhoden over 1 year ago the error from sys.exitfunc should only come from an exception raised from functions executed at interpreter shutdown. import atexit import sys def all_done(): print 'all_done()' print 'Registering' atexit.register(all_done) print 'Registered' print 'Exiting...' sys.exit() $ python atexit_sys_exit.py Registering Registered Exiting...
sys.exc_type¶ sys.exc_value¶ sys.exc_traceback¶ Deprecated since version 1.5: Use exc_info() instead. check my blog New in version 2.3. sys.modules¶ This is a dictionary that maps module names to modules which have already been loaded. import atexit def my_cleanup(name): print 'my_cleanup(%s)' % name atexit.register(my_cleanup, 'first') atexit.register(my_cleanup, 'second') atexit.register(my_cleanup, 'third') Notice that order in which the exit functions are called is the reverse of the order they
If Python is unable to retrieve the real path to its executable, sys.executable will be an empty string or None. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH. Some systems have a convention for assigning specific meanings to specific exit codes, but these are generally underdeveloped; Unix programs generally use 2 for command line syntax errors and 1 for http://caribtechsxm.com/python-error/python-error-function-2-6.php Symbolic names for the flag modules can be either found in the dl module, or in the DLFCN module.
Since most functions don't need access to the traceback, the best solution is to use something like exctype, value = sys.exc_info()[:2] to extract only the exception type Python Runtime Services Next topic 28.2. sysconfig -- Provide access to Python's configuration information This Page Report a Bug Show Source Quick search Enter search terms or a module, class Something like that : import sys import atexit def clear_atexit_excepthook(exctype, value, traceback): atexit._exithandlers[:] =  sys.__excepthook__(exctype, value, traceback) def helloworld(): print "Hello world!" sys.excepthook = clear_atexit_excepthook atexit.register(helloworld) raise Exception("Good bye cruel
It is not guaranteed to exist in all implementations of Python. Setting it to a larger value may increase performance for programs using threads. The result value depends on the operating system: On Mac OS X, the encoding is 'utf-8'. Word for making your life circumstances seem much worse than they are Can I use my client's GPL software?
Skip to content Ignore Learn more Please note that GitHub no longer supports old versions of Firefox. Otherwise, float_repr_style has value 'legacy' and repr(x) behaves in the same way as it did in versions of Python prior to 2.7. THis happens if sys.exitfunc has been set directly (a deprecated feature), or using the 'atexit' module. have a peek at these guys If it's a hang then I have something to work with.
arg depends on the event type. hsaliak added this to the GA milestone May 16, 2016 hsaliak added the P2 label May 16, 2016 hsaliak modified the milestone: 2016/05/21 Milestone, GA May 16, 2016 kpayson64 commented Jun GuoJing commented Feb 7, 2016 May be one way but not the best way to solve: import atexit global _client_impls _client_impls =  class X: def __init__(self): self.connect() def connect(self): self.ch In particular, sys.exit("some error message") is a quick way to exit a program when an error occurs.
sys.ps1¶ sys.ps2¶ Strings specifying the primary and secondary prompt of the interpreter. Something about Nintendo and Game Over Screen A Riddle - Mountains and Valleys Why do neural network researchers care about epochs? This integer value determines how often the interpreter checks for periodic things such as thread switches and signal handlers. Its behavior is part of the implementation platform, rather than part of the language definition, and thus may not be available in all Python implementations. sys.settscdump(on_flag)¶ Activate dumping of VM
New in version 2.6. Reports have also come from RHEL 6 and SLES 11 distros. sys.getcheckinterval()¶ Return the interpreter's "check interval"; see setcheckinterval(). soltanmm referenced this issue Feb 5, 2016 Closed Python process hangs on exit #5084 inconshreveable commented Feb 5, 2016 This hangs: import sys from grpc.beta import implementations import helloworld_pb2 class X:
The main collection of Python library modules is installed in the directory prefix/lib/pythonX.Y while the platform independent header files (all except pyconfig.h) are stored in prefix It is removed in Python 3.3. This is most useful for debugging deadlock: this function does not require the deadlocked threads' cooperation, and such threads' call stacks are frozen for as long as they remain deadlocked. sys.getprofile()¶ Get the profiler function as set by setprofile(). Thanks and Best wishes Sorry for poor English. sys.getrecursionlimit()¶ Return the current value of the recursion limit, the maximum depth of the Python interpreter stack.
