Python输入时

Question

为什么这样不行？我输入windows/meterpreter/reverse_tcp，它再次返回错误

def shellcode():
    os.system("clear")
    print style
    print green + "  [+]Your Choose 4 | C Type Format - ShellCode Generate"
    print style
    print payload_types
    print ' '
    payload_choose = raw_input(time + white + "Choose Payload > ")
    while (payload_choose != "windows/meterpreter/reverse_tcp" or "linux/x86/meterpreter/reverse_tcp"):
        print "[-]error"
        payload_choose = raw_input(time + white + "Choose Payload > ")
    print "ok"

Answer 1

这条线：

while (payload_choose != "windows/meterpreter/reverse_tcp" or "linux/x86/meterpreter/reverse_tcp"):

可能做不到你想做的。我想你可能是这个意思？你知道吗

while payload_choose != "windows/meterpreter/reverse_tcp" and payload_choose != "linux/x86/meterpreter/reverse_tcp":

进一步解释

此表达式：

a or b

意思是“a为真或b为真”。你知道吗

此表达式：

foo != 'hello' or 'goodbye'

意思是“福！='你好'）是真的或'再见'是真的。在Python中，非空字符串被认为是“truthy”，因此原始的while循环条件始终为true。你知道吗
