 """
 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.

 stdin -- standard input file object; used by input()
 stdout -- standard output file object; used by print()
 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.

 Static objects:

 builtin_module_names -- tuple of module names built into this interpreter
 copyright -- copyright notice pertaining to this interpreter
 exec_prefix -- prefix used to find the machine-specific Python library
 executable -- absolute path of the executable binary of the Python interpreter
 float_info -- a struct sequence with information about the float implementation.
 float_repr_style -- string indicating the style of repr() output for floats
 hash_info -- a struct sequence with information about the hash algorithm.
 hexversion -- version information encoded as a single integer
 implementation -- Python implementation information.
 int_info -- a struct sequence with information about the int implementation.
 maxsize -- the largest supported length of containers.
 maxunicode -- the value of the largest Unicode code point
 platform -- platform identifier
 prefix -- prefix used to find the Python library
 thread_info -- a struct sequence with information about the thread implementation.
 version -- the version of this interpreter as a string
 version_info -- version information as a named tuple
 dllhandle -- [Windows only] integer handle of the Python DLL
 winver -- [Windows only] version number of the Python DLL
 _enablelegacywindowsfsencoding -- [Windows only]
 __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 builtins._
 excepthook() -- print an exception and its traceback to sys.stderr
 exc_info() -- return thread-safe information about the current exception
 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
