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)
