### 1.获取python路径 ###

python:~ #python3
    Python 3.5.2 (default, Feb  6 2020, 00:14:34) 
    [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import sys
    >>> sys.path
    ['', '/usr/local/python/lib/python35.zip', '/usr/local/python/lib/python3.5', '/usr/local/python/lib/python3.5/plat-linux', '/usr/local/python/lib/python3.5/lib-dynload', '/usr/local/python/lib/python3.5/site-packages']

### 2.创建tab py文件 ###

python:~ #cd /usr/local/python/lib/python3.5/site-packages
    
    python:/usr/local/python/lib/python3.5/site-packages #cat tab.py 
    #!/usr/local/python/bin/python3
    # 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

### 3.安装readline ###

pip3 install readline
