程序如下（Python Tutorial Python3.7.1节）：
def ask_ok(prompt, retries=4, complaint='Yes or no, please!'):
    while 1:
        ok = raw_input(prompt)
        if ok in ('y', 'ye', 'yes'):
            return True
        if ok in ('n', 'no', 'nop', 'nope'):
            return False
        retries = retries - 1
        if retries < 0:
            raise IOError, 'refusenik user'
        print complaint

while 1:
    flag = ask_ok('are you really want to quit?')
    if flag == True:
        break
print 'out'

在Eclipse里面不管输入什么，都输出Yes or no, please!
而在IDLE下面运行结果是正确的。
是Pydev的bug吗？
请教！

在Eclipse里把OK的值打出来看看，可能输入的值被改动了。

设置断点后，发现问题处在哪儿了。
我输入一个字符串后按回车，所以ok的后面加了'\r'
将程序改为：
def ask_ok(prompt, retries=4, complaint='Yes or no, please!'):
    while 1:
        ok = raw_input(prompt)
        print ok
        if ok in ('y\r', 'ye\r', 'yes\r'):
            return True
        if ok in ('n\r', 'no\r', 'nop\r', 'nope\r'):
            return False
        retries = retries - 1
        if retries < 0:
            raise IOError, 'refusenik user'
        print complaint

while 1:
    flag = ask_ok('are you really want to quit?')
    if flag == True:
        break
print 'out'
在Eclipse里面运行结果正确。（当然，在IDLE里面运行就错了:(  )

看来在Eclipse和IDLE中对输入的处理不一样：Eclipse把回车既当作输入的结束符也当作了输入值的一部分；而IDLE只把回车当作输入的结束符。

ok= raw_input(prompt)
之后加一个 ok = ok.strip()
我这儿pydev1.2.1也有这个问题，看起来是对\r\n处理的不好吧
