用 Python shell 没有 Tab 补全还是挺痛苦的，下面就记录一下如何补全：
1. 先准备一个 tab.py 的脚本。
>>> tap.py
1 #!/usr/bin/python 2 # python tab file 3 4 import sys 5 import readline 6 import rlcompleter 7 import atexit 8 import os 9 # tab completion 10 readline.parse_and_bind('tab: complete') 11 # history file 12 histfile = os.path.join(os.environ['HOME'], '.pythonhistory') 13 try: 14 readline.read_history_file(histfile) 15 except IOError: 16 pass 17 atexit.register(readline.write_history_file, histfile) 18 19 del os, histfile, readline, rlcompleter
2. 查看Python默认的模块存放地址
1 Python 3.6.3 (v3.6.3:2c5fef8, Oct 3 2017, 18:22:56) [MSG v.1900 64 bit (AMD64)] on win32 2 Type "help", "copyright", "credits" or "license" for more information. 3 >>> import string 4 >>> string .__file__ 5 'C:\Users\Administrator\AppData\Local\Programs\Python\Python36\lib\string.py'
3. 拷贝该脚本到默认模块存放路径
>>> 'C:\Users\Administrator\AppData\Local\Programs\Python\Python36\lib\'
4. 现在可以用了.hhhhhhhhhhh
