此代码检查系统是Windows还是Linux,导入所需的库,并定义正常工作的“getch”功能。
但是......函数“_d”可以在lambda中完成吗?
def _d():
import sys, tty, termios
f = sys.stdin.fileno()
o = termios.tcgetattr(f)
try:
tty.setraw(sys.stdin.fileno())
c = sys.stdin.read(1)
finally:
termios.tcsetattr(f, termios.TCSADRAIN, o)
return c
_u = type('', (), {
'__init__': lambda s: setattr(s, '', (None for sys in [__import__('sys')] for tty in [__import__('tty')])),
'__call__': _d()
})
_w = None if ImportError else __import__("msvcrt").getch()
getch = (type('', (), {
'__init__': lambda s: setattr(s, 'i', _u()) if ImportError else setattr(s, 'i', _w()),
'__call__': lambda s: s.i()
}))()
我目前有:
setattr(type('',(),{}), '', (
None for sys in [__import__('sys')]
for tty in [__import__('tty')]
for termios in [__import__('termios')]
for f in sys.stdin.fileno()
for o in termios.tcgetattr(f)
for _ in tty.setraw(sys.stdin.fileno())
for c in sys.stdin.read(1)
for _ in termios.tcsetattr(f, termios.TCSADRAIN, o)
))
但那不让我回“c”。
答案 0 :(得分:0)
好吧,如果你必须:
lambda: exec("""
def _d():
import sys, tty, termios
f = sys.stdin.fileno()
o = termios.tcgetattr(f)
try:
tty.setraw(sys.stdin.fileno())
c = sys.stdin.read(1)
finally:
termios.tcsetattr(f, termios.TCSADRAIN, o)
return c
""", globals()) or _d()
它似乎比其他选择更具可读性。
要修复您给定的代码,请尝试:
lambda: next(
c
for sys in [__import__('sys')]
for tty in [__import__('tty')]
for termios in [__import__('termios')]
for f in [sys.stdin.fileno()]
for o in [termios.tcgetattr(f)]
for _ in [tty.setraw(sys.stdin.fileno())]
for c in [sys.stdin.read(1)]
for _ in [termios.tcsetattr(f, termios.TCSADRAIN, o)]
)
