I would like to create interactive Python script (probably using curses?) with menu where user can navigate over menu using keyboard arrows.
What is the easiest way to implement such functionality? Any simple usage/tutorial?
Thank You!
take a look at Python curses module and for example ncurses-ui-python.
There are alternatives like Urwid and Pycdk
You might wanto to take a look also at snack (newt-based library)
You might also want to check out Unicurses, which wraps python's native curses module in linux and pdcurses in Windows.
Unicurses has the benefit of maintaining a style of usage which is consistent with nCurses and PDCurses. Therefore, tutorials such as this one will be more helpful if you're wrapping puthon curses with unicurses.

I'm looking for a Python 3.x library that is able to allow interaction with other programs.
For example, I already have some sort of command-line interface which I have developed in python, and I
want to be able to enter, say "1", and have another program open. From here, I wish to hit another
input like "2" and have it manipulate the GUI that opens (for example, for it to "click" the Configurations
dropdown bar and select an option, perhaps modify a few settings, apply, and then possibly also automatically
enter some text). The reason I'm doing this is for test automation.
I've already tried using pywinauto, but I've found it to not be compatible for Python 3! :(
Is there another possible approach to this? Thanks in advance!!!
P.S. I may have forgotten to mention that I'm using Windows 7 but with Python32
You could look into sikuli. It lets you automate clicks and other actions based on region or matched graphic. Fairly smart. Is there a reason you're dead set on using py3?
Py3-compatible pywinauto released! New home page: http://pywinauto.github.io/
P.S. I'm maintainer of pywinauto.
Late answer, but have a look at pyautogui which enables you to move the mouse and press keys. I used it for the following snippet which launches an emulator and presses keys.
import pyautogui as pg
import os
import time
game_filepath = "../games/BalloonFight.zip"
os.system(f"fceux {game_filepath} &")
time.sleep(1)
keys_to_press = ['s', 's', 'enter']
for key_to_press in keys_to_press:
pg.keyDown(key_to_press)
pg.keyUp(key_to_press)
time.sleep(2)
im = pg.screenshot("./test.png", region=(0,0, 300, 400))
print(im)

I created a pywinauto fork on GitHub that's compatible with Python 3:

I only did basic testing, so there might still be some circular import related problems that I haven't found.
I need text-console interactive dialogs. I am porting a shell script to Python. Which Python tool would do pretty much exactly what the UNIX command dialog does? (i.e. ready-to-use yes/no, calendar, text, gauge, etc. controls which return results and are ncurses-like full-screen UIs)
You should look at Urwid.
Urwid provides a higher-level toolkit on top of curses and includes an event loop to handle keyboard and mouse input. It either uses it's own select-based event loop, or can hook into gevent or Twisted.
In addition to handling keyboard input efficiently you'll also have a host of options to handle user input with edit boxes, list controls and more.
Have a look at curses. It's low-level, but has the advantage of being a part of the standard library.
These are dialog Python bindings: http://pythondialog.sourceforge.net/
I'm not even sure what these would be called? I used to write them in ADA running on VAX-VMS!
I want to make a simple menu-driven application that would let me display menus and use the cursor keys to navigate around them, choose items and navigate around the app. All fully old school text based.
I want to be able to take over the whole terminal window and display stuff in different places.
Is this possible in Python?
Check out the Python HOWTO on Curses Programming with Python and here is the library reference.
Another easy to use library is Urwid - Console User Interface Library.

Yes, have a look at the different curses implementations.
I'm looking for a cross-platform way of making my Python script process a file's path by implementing a drag n drop method. At the moment I manually go to the terminal and use the sys.argv method:
python myscript.py /Python/myfile.xls
However this is slow and "techy". Ideally I would a quick and interactive way of allowing a file be processed by my Python script. I primarily need this to work for Mac but cross-platform would be better.
If you want to use Tkinter, have a look at the Tkinter DnD binding from here http://klappnase.bubble.org/TkinterDnD/index.html
When run, the binding shows an example with a listbox that allows you to drag a file on to it.
Do you want to drag and drop the myfile.xls onto your python script within your file navigator ? Say Finder or whatever on Mac, Explorer on Win, Nautilus etc. ? In that case there will not be a simple cross-platform solution, given that you will have to hook into different software on different systems.
For a Mac specific solution try AppleScript - here is a sample
And for something Pythonic there is http://appscript.sourceforge.net/ , http://docs.python.org/library/macosa.html
Otherwise the solution is in the answer above. Use a custom GUI built in Tk, or wx or QT. You can look up their respective documentation for drag and drop, they do have cross-platform ways of doing it.
It'd be easiest to just write a small GUI with Tkinter or something similar and have the user select a file from within the GUI. Something along these lines:
import tkFileDialog
f = tkFileDialog.askopenfilename()
# Go on from there; f is a handle to the file that the user picked
I'm not aware of any cross platform methods to get a script to work with drag and drop, however. This is probably easier, though.
I am planning to do the folliwing:
Create a PyGtk GUI (hardcoded, no Glade) with some widgets, and at the bottom of the screen put some sort of VTE (Virtual Terminal Emulator) from where I could manipulate the widgets, for example changing their attributes and calling their methods from the commandline.
The result would be similar to using AutoCAD's commands, only that I would be acting upon the GUI objects.
I have already found very few things about gtk.VteTerminal widget, but not only could not find a working example or make one myself, it also seem to be a system terminal, not a "current session" python terminal where I could run python commands and access GUI objects.
Any suggestion?
Thanks for reading
What you want exists already: GtkParasite. It's meant for debugging, but I'm sure if you wanted it to actually be a part of your application, you could adapt it.
I'm late to the party, but I had a similar problem.
Look here
Virtual Terminal Question
It's an option if you decide to do something different than what you might have already done.
