Win10 (PowerShell) under Python Command line tab auto Completion

Use Python to debug simple programs directly from the command line.

WIN10 (PowerShell) Without tab completion, the operation is really troublesome.

Online search learned, record, review with, hahaha

Environment: WIN10 64-bit Python2,python3One: Install the Pyreadline module

Pip Install Pyreadline # python2pip3 install Pyreadline # Python3

Ii. Preparation of tab.py

File saved in: \python2\lib\tab.py

例如：D:\Program Files\Python2\Lib\tab.py
python2 python3要使用TAb自动补全都要在对应的lib中建立tab.py文件

#python tabimport sys   import readline   import rlcompleter   import atexit   import os    readline.parse_ And_bind (' Tab:complete ')   # windowshistfile = 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  

Third, the effect test

Use Import tab to introduce tab completion

# Python2

# Python3

# After testing found that Python2 need to import tab to support auto-completion, and then python3 do not need to import tab to support auto-completion, do not know that is not my more special??
