This module provides access to some objects used or maintained by the interpreter and to functions that interact strongly with the interpreter. Dynamic objects: argv -- command line arguments; argv[0] is the script pathname if known path -- module search path; path[0] is the script directory, else '' modules -- dictionary of loaded modules displayhook -- called to show results in an interactive session excepthook -- called to handle any uncaught exception other than SystemExit To customize printing in an interactive session or to install a custom top-level exception handler, assign other functions to replace these. exitfunc -- if sys.exitfunc exists, this routine is called when Python exits Assigning to sys.exitfunc is deprecated; use the atexit module instead. stdin -- standard input file object; used by raw_input() and input() stdout -- standard output file object; used by the print statement stderr -- standard error object; used for error messages By assigning other file objects (or objects that behave like files) to these, it is possible to redirect all of the interpreter's I/O. last_type -- type of last uncaught exception last_value -- value of last uncaught exception last_traceback -- traceback of last uncaught exception These three are only available in an interactive session after a traceback has been printed. exc_type -- type of exception currently being handled exc_value -- value of exception currently being handled exc_traceback -- traceback of exception currently being handled The function exc_info() should be used instead of these three, because it is thread-safe. Static objects: float_info -- a dict with information about the float inplementation. long_info -- a struct sequence with information about the long implementation. maxint -- the largest supported integer (the smallest is -maxint-1) maxsize -- the largest supported length of containers. maxunicode -- the largest supported character builtin_module_names -- tuple of module names built into this interpreter version -- the version of this interpreter as a string version_info -- version information as a named tuple hexversion -- version information encoded as a single integer copyright -- copyright notice pertaining to this interpreter platform -- platform identifier executable -- absolute path of the executable binary of the Python interpreter prefix -- prefix used to find the Python library exec_prefix -- prefix used to find the machine-specific Python library float_repr_style -- string indicating the style of repr() output for floats __stdin__ -- the original stdin; don't touch! __stdout__ -- the original stdout; don't touch! __stderr__ -- the original stderr; don't touch! __displayhook__ -- the original displayhook; don't touch! __excepthook__ -- the original excepthook; don't touch! Functions: displayhook() -- print an object to the screen, and save it in __builtin__._ excepthook() -- print an exception and its traceback to sys.stderr exc_info() -- return thread-safe information about the current exception exc_clear() -- clear the exception state for the current thread exit() -- exit the interpreter by raising SystemExit getdlopenflags() -- returns flags to be used for dlopen() calls getprofile() -- get the global profiling function getrefcount() -- return the reference count for an object (plus one :-) getrecursionlimit() -- return the max recursion depth for the interpreter getsizeof() -- return the size of an object in bytes gettrace() -- get the global debug tracing function setcheckinterval() -- control how often the interpreter checks for events setdlopenflags() -- set the flags to be used for dlopen() calls setprofile() -- set the global profiling function setrecursionlimit() -- set the max recursion depth for the interpreter settrace() -- set the global debug tracing function

Return a dictionary mapping each current thread T's thread id to T's current stack frame. This function should be used for specialized purposes only.
|
Return a frame object from the call stack. If optional integer depth is given, return the frame object that many calls below the top of the stack. If that is deeper than the call stack, ValueError is raised. The default for depth is zero, returning the frame at the top of the call stack. This function should be used for internal and specialized purposes only.
|
Call func(*args), while tracing is enabled. The tracing state is saved, and restored afterwards. This is intended to be called from a debugger from a checkpoint, to recursively debug some other code.
|
Return a tuple of function call statistics, if CALL_PROFILE was defined when Python was built. Otherwise, return None. When enabled, this function returns detailed, implementation-specific details about the number of function calls executed. The return value is a 11-tuple where the entries in the tuple are counts of: 0. all function calls 1. calls to PyFunction_Type objects 2. PyFunction calls that do not create an argument tuple 3. PyFunction calls that do not create an argument tuple and bypass PyEval_EvalCodeEx() 4. PyMethod calls 5. PyMethod calls on bound methods 6. PyType calls 7. PyCFunction calls 8. generator calls 9. All other calls 10. Number of stack pops performed by call_function()
|
Clear global information on the current exception. Subsequent calls to exc_info() will return (None,None,None) until another exception is raised in the current thread or the execution stack returns to a frame where another exception is being handled.
|
Exit the interpreter by raising SystemExit(status). If the status is omitted or None, it defaults to zero (i.e., success). If the status is an integer, it will be used as the system exit status. If it is another kind of object, it will be printed and the system exit status will be one (i.e., failure). |
Return the current value of the flags that are used for dlopen calls. The flag constants are defined in the ctypes and DLFCN modules.
|
Return the profiling function set with sys.setprofile. See the profiler chapter in the library manual. |
Return the current value of the recursion limit, the maximum depth of the Python interpreter stack. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python. |
Return the reference count of object. The count returned is generally one higher than you might expect, because it includes the (temporary) reference as an argument to getrefcount().
|
Return the global debug tracing function set with sys.settrace. See the debugger chapter in the library manual. |
Tell the Python interpreter to check for asynchronous events every n instructions. This also affects how often thread switches occur. |
Set the flags used by the interpreter for dlopen calls, such as when the interpreter loads extension modules. Among other things, this will enable a lazy resolving of symbols when importing a module, if called as sys.setdlopenflags(0). To share symbols across extension modules, call as sys.setdlopenflags(ctypes.RTLD_GLOBAL). Symbolic names for the flag modules can be either found in the ctypes module, or in the DLFCN module. If DLFCN is not available, it can be generated from /usr/include/dlfcn.h using the h2py script.
|
Set the profiling function. It will be called on each function call and return. See the profiler chapter in the library manual. |
Set the maximum depth of the Python interpreter stack to n. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python. The highest possible limit is platform- dependent. |
Set the global debug tracing function. It will be called on each function call. See the debugger chapter in the library manual. |
