尽管它特定于X，但是您可以安装xautomation软件包（apt-get install xautomation在基于Debian的系统上）并用于xte模拟按键，例如：
from subprocess import Popen, PIPE
control_f4_sequence = '''keydown Control_L
key F4
keyup Control_L
'''
shift_a_sequence = '''keydown Shift_L
key A
keyup Shift_L
'''
def keypress(sequence):
p = Popen(['xte'], stdin=PIPE)
p.communicate(input=sequence)
keypress(shift_a_sequence)
keypress(control_f4_sequence)
