CMD auto-completion not working correctly

(Python 3.3.4)

I am currently using the cmd module to build an application, but for some reason I just can't get the completion to work correctly. Whenever I hit tab it just indents my input string!!

So, if I have something like this: (MyShell)>> ta«cursor here» I hit «tab» and get this: (MyShell)>> ta «cursor here»

I have tried in IDLE, the Windows Power Shell and in the Python interpreter itself, I guess... Neither the completion of commands nor the completion of arguments work!!

The code is this:

class MyShell(cmd.Cmd):

    def __init__(self):
        cmd.Cmd.__init__(self)
        self.intro = "Welcome to MyShell test.\nPowered by Rodrigo Serrão"
        self.prompt = "(MyShell)>>"

    def do_talk(self, text):
        print("Hello")

    stuff = ["blabla", "bananas!", "noodles"]
    def complete_talk(self, text, line, s, e):
        if text:
            return [i for i in stuff if i.startswith(text)]
        else:
            return stuff


MyShell().cmdloop()

I have read some questions about this, including this one: Python Cmd Tab Completion Problems

And it may have to do with that readline thing. I tried to import it, but apparently I don't have it.

if it is a problem of your check this approach.

Go to run and type regedit.

Go to LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor.

And change the PathCompletionChar value to 9. Usually it is 40. That means your current auto completion key is not the TAB key. After you assign the value 9 close the window and restart the CMD.

Now this would be fixed. Auto completion of paths would be working fine by the TAB key.

So I'm writing a interactive shell app on Python too, to get auto completion working, install pyreadline, the readline module is Unix specific.

If you don't know how install just execute the following line:

pip install pyreadline
