问题
I am writing a script to automate running a particular model. When the model fails, it waits for a user input (Enter key). I can detect when the model has failed, but I am not able to use python (on linux) to simulate a key press event. Windows has the SendKeys library to do this but I was wondering if there is a similar library for python on linux.
Thanks!

If the "model" is running graphically (with the X window system), the already-suggested xsendkey is a possibility, or xsendkeycode. If it's running textually (in a terminal window), then pexpect.

Have a look at this https://github.com/SavinaRoja/PyUserInput its cross-platform control for mouse and keyboard in python
Keyboard control works on X11(linux) and Windows systems. But no mac support(when i wrote this answer).
from pykeyboard import PyKeyboard
k = PyKeyboard()
# To Create an Alt+Tab combo
k.press_key(k.alt_key)
k.tap_key(k.tab_key)
k.release_key(k.alt_key)

A more low-level approach would be to create an uinput device from which you would then inject input events into the linux input subsystem. Consider the following libraries:
- python-uinput
- evdev
Example of sending <enter> with the latter:
from evdev import uinput, ecodes as e
with uinput.UInput() as ui:
ui.write(e.EV_KEY, e.KEY_ENTER, 1)
ui.write(e.EV_KEY, e.KEY_ENTER, 0)
ui.syn()

I recommend PyAutoGui. It's ridiculously simple to use, it's cross-platform and it's for Python 3 and 2.
In the linked page are listed the dependences and some code examples.
