win环境下python tab键补全

1,首先打开cmd窗口执行以下命令安装readline模块

python -m pip install pyreadline

 2,编写 tab.py 

#python Tab
import sys   
import readline   
import rlcompleter   
import atexit   
import os    
readline.parse_and_bind('tab: complete')   
# windows
histfile = os.path.join(os.environ['HOMEPATH'], '.pythonhistory')   
# linux
# 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

放到Python安装目录

比如我的python安装在C:\Python3 目录

放到同级目录C:\Python3\tab.py

3，测试
