我试图匹配一个字符串，比如“Gujia”，然后执行一个特定的shell脚本，但是无论我输入什么，它总是运行第一个循环，我尝试注释“Gujia”的大小写，但它也只是继续调用顶部的if/elseif循环

Answer 1

您似乎犯了以下几个错误

1. show=raw_input("What do you want to see? \n")需要在while 1循环中，我认为
2. 遗憾的是，对于字符串比较，您需要使用==
3. show is 'Gujia' or 'gujia'实际上是{}。而且'guija'不是空字符串，它始终是真的
4. 有很多elif input ...，但“输入”可能是“显示”，不是吗

因此，综合考虑这些条件：

while 1:
    show=raw_input("What do you want to see? \n")
    show = show.lower() # translate strings to lower case.
    if show == 'gujia': 
        call(['bash','gujia.sh'])
        termios.tcflush(sys.stdin, termios.TCIOFLUSH)
#   subprocess.call(["gujia.sh"])
    elif show == 'dal bati churma':
        call(['bash','dbc.sh'])
    ...

Answer 2

show=raw_input("What do you want to see? \n")
while 1:
    if show in ('Gujia', 'gujia'): 
        call(['bash','gujia.sh'])
        termios.tcflush(sys.stdin, termios.TCIOFLUSH)
        break

试试上面的这个方法，它会起作用的

如果显示在（'words'、'..'、'..'、'..'、'..'中） 它将搜索匹配的单词，如果其中一个匹配，则执行代码
