Python 中的tab补全

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
