用Python时候没有TAB补全，挺痛苦的，以下是添加方法
代码语言：javascript复制1.准备一个Python脚本 cat > tab.py <<EOF #!/usr/local/bin/python # python tab file import sys import readline import rlcompleter import atexit import os # tab completion readline.parse_and_bind('tab: complete') # history file histfile = os.path.join(os.environ['HOME'], '.pythonhistory') try: readline.read_history_file(histfile) except IOError: pass atexit.register(readline.write_history_file, histfile) del os, histfile, readline, rlcompleter EOF 2.查看Python默认的模块存放位置 [root@victor python2.7]# python Python 2.7.6 (default, Sep 17 2017, 04:41:33) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path ['', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages'] 3.拷贝到目录下 cp tab.py /usr/local/lib/python2.7 4.现在可以用了 [root@victor python]# cp tab.py /usr/local/lib/python2.7 [root@victor python]# python Python 2.7.6 (default, Sep 17 2017, 04:41:33) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import tab >>> import sys >>> sys. sys.__class__( sys.__sizeof__( sys.displayhook( sys.getprofile( sys.ps1 sys.__delattr__( sys.__stderr__ sys.dont_write_bytecode sys.getrecursionlimit( sys.ps2 sys.__dict__ sys.__stdin__ sys.exc_clear( sys.getrefcount( sys.py3kwarning sys.__displayhook__( sys.__stdout__ sys.exc_info( sys.getsizeof( sys.setcheckinterval( sys.__doc__ sys.__str__( sys.exc_type sys.gettrace( sys.setdlopenflags( sys.__excepthook__( sys.__subclasshook__( sys.excepthook( sys.hexversion sys.setprofile( sys.__format__( sys._clear_type_cache( sys.exec_prefix sys.long_info sys.setrecursionlimit( sys.__getattribute__( sys._current_frames( sys.executable sys.maxint sys.settrace( sys.__hash__( sys._getframe( sys.exit( sys.maxsize sys.stderr sys.__init__( sys._mercurial sys.exitfunc( sys.maxunicode sys.stdin sys.__name__ sys.api_version sys.flags sys.meta_path sys.stdout sys.__new__( sys.argv sys.float_info sys.modules sys.subversion sys.__package__ sys.builtin_module_names sys.float_repr_style sys.path sys.version sys.__reduce__( sys.byteorder sys.getcheckinterval( sys.path_hooks sys.version_info sys.__reduce_ex__( sys.call_tracing( sys.getdefaultencoding( sys.path_importer_cache sys.warnoptions sys.__repr__( sys.callstats( sys.getdlopenflags( sys.platform sys.__setattr__( sys.copyright sys.getfilesystemencoding( sys.prefix
