  • If has VsCode use cmd and copy this
  • code C:\SP_CI_PROGRAMS\Languages\Python\3.6.1\Lib\rlcompleter.py
• Look the line 80 which traceback tell us
• Change these line (starts 79) like bellow and It will works
• There will no error message and unnecessary tab more

...
if _readline_available:                  ## The old one is ##
    if hasattr(readline, 'redisplay'):   # if _readline_available:
        readline.insert_text('\t')       #     readline.insert_text('\t')
        readline.redisplay()             #     readline.redisplay()
    return ''                            # return ''
