tab Auto-completion in Python interactive mode

In interactive mode, Python presses the TAB key for the function output of the Time tab key when entering a command, which is inconvenient when writing python.

Write the following code into a file tab.py, and put it under/usr/lib/python2.6/site-packages/.

#!/usr/bin/env pythonimport sysimport readlineimport rlcompleterimport atexitimport osreadline.parse_and_bind (' tab: Complete ') Histfile = Os.path.join (os.environ[' HOME '), '. Pythonhistory ') try:readline.read_history_file (histfile) Except Ioerror:pass Atexit.register (Readline.write_history_file,histfile)

How to use:

Python enters interactive mode:

>>> import tab>>> import sys>>> sys.sys.__class__ (               sys.api_version              SYS.HEXVERSIONSYS.__DELATTR__ (             sys.argv                     sys.last_type (sys.__dict__                 sys.builtin_module_ names    sys.last_valuesys.__displayhook__ (         sys.byteorder                sys.maxintsys.__doc__                  sys.call_tracING (           sys.maxsizesys.__egginsert              sys.callstats (               sys.maxunicodesys.__excepthook__ (          sys.copyright                sys.meta_pathsys.__format__ (              sys.displayhook (             SYS.MODULESSYS.__GETATTRIBUTE__ (       sys.dont_write_bytecode      sys.pathsys.__hash__ (                sys.exc_clear (               sys.path_hookssys.__init__ (                Sys.exc_info (                sys.path_importer_cachesys.__name__                 sys.exc_type                 sys.platformsys.__new__ (                 sys.excepthook (              sys.prefixsys.__package__              sys.exec_prefix              sys.ps1sys.__plen                   sys.executable              SYS.PS2SYS.__REDUCE__ (              sys.exit (                     Sys.py3kwarningsys.__reduce_ex__ (          sys.exitfunc (                sys.setcheckinterval (Sys.__repr__ (                sys.flags                    sys.setdlopenflags (sys.__setattr__ (             sys.float_info               sys.setprofile (sys.__sizeof__ (  &nbsP;          sys.getcheckinterval (        sys.setrecursionlimit (sys.__stderr__               sys.getdefaultencoding (     sys.settrace (sys.__stdin__                sys.getdlopenflags (          sys.stderrsys.__stdout__               sys.getfilesystemencoding (  sys.stdinsys.__str __ (                 Sys.getprofile (             sys.stdoutsys.__ Subclasshook__ (       sys.getrecursionlimit (       sys.subversionsys._clear_tYpe_cache (      sys.getrefcount (             sys.versionsys._current_frames (         Sys.getsizeof (              sys.version_ Infosys._getframe (               Sys.gettrace (                Sys.warnoptions>>> sys.

This makes it easy to view the function modules.
