Python hitting tab fails with Python AttributeError: module 'readline' has no attribute 'redisplay'

Question

Using Python 3.7.3 (Anaconda) on Windows, hitting tab results in the following traceback:

Readline internal error
Traceback (most recent call last):
  File \"C:\         


        

Answer 1

The Anaconda module readline is different from the standard Python readline which does have the method redisplay. The workaround I found to make this work was disabling the autocomplete. To archive that you need to set as True the attribute disable_readline in the file rlmain.py line 58.

..\Anaconda3\Lib\site-packages\pyreadline\rlmain.py

class BaseReadline(object):
    def __init__(self):
        self.allow_ctrl_c = False
        self.ctrl_c_tap_time_interval = 0.3

        self.debug = False
        self.bell_style = 'none'
        self.mark = -1
        self.console=MockConsole()
        self.disable_readline = True # Old value: False
