Python全局名称未在第一个函数中定义，但在第二个函数中

Question

我在python 2.7.10下遇到一个奇怪的问题，这是我的代码的相关部分：

...

#is called whenever the reinitscore() is called, and if the if statement is correct
def calculateWinner(d):
    scores = {}
    high_score = 0

    for key, value in d.items():
        try:
            scores[value].append(key)
        except KeyError:
            scores[value] = [key]
        if value > high_score:
            high_score = value
    results = scores[high_score]

    if len(results) == 1:
        print results[0]
        stelnet.send(results[0])
        return results[0]
    else:
        print 'TIE'
        return 'TIE', results

#is called once, then every 5 seconds automatically with threading
def reinitScore():
    threading.Timer(5, reinitScore).start()
    global leftKeyCounter
    global rightKeyCounter
    global frontKeyCounter
    global backKeyCounter

    values = {'left' : leftKeyCounter, 'right' : rightKeyCounter, 'front' : frontKeyCounter, 'back' : backKeyCounter}

    if (leftKeyCounter != 0 or rightKeyCounter != 0 or frontKeyCounter != 0 or backKeyCounter != 0):
        calculateWinner(values)
        leftKeyCounter = 0
        rightKeyCounter = 0
        frontKeyCounter = 0
        backKeyCounter = 0
        print "back to 0"
    else:
        stelnet.send("test")

if __name__ == "__main__":
    if(len(sys.argv) < 3):
        print 'Usage : python telnet.py hostname port'
        sys.exit()

    host = sys.argv[1]
    port = int(sys.argv[2])

    stelnet = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    stelnet.settimeout(2)

    # connect to remote host
    try:
        stelnet.connect((host, port))
    except:
        print 'Unable to connect'
        sys.exit()

...

while 1:
    socket_list = [sys.stdin, stelnet]

    # Get the list sockets which are readable
    read_sockets, write_sockets, error_sockets = select.select(socket_list , [], [])

    for sock in read_sockets:
        #incoming message from remote server
        if sock == stelnet:
            data = sock.recv(4096)
            if not data:
                print 'Connection closed'
                sys.exit()
            else:
                #print data
                sys.stdout.write(data)

        #user entered a message
        else:
            msg = sys.stdin.readline()
            stelnet.send(msg)

所以这里发生了什么：calculateWinner（）由reinitScore调用，并通过telnet连接发送结果。在calculateWinner（）函数中发送telnet没有问题，但是当我想在reinitScore（）中使用stelnet.send（）时，他返回这个

NameError：全球名称＆＃39; stelnet＆＃39;未定义

很奇怪，我可以在函数中使用stelnet.send，彼此相邻，而不是在另一个函数中......

另外，我的python一直在给我

unindentend错误

这非常烦人，因为我只使用制表符而不是任何空格，他甚至强迫我使用unindent部分（请参阅reinitScore（）的结尾）以接受运行代码......

我正在使用Sublime Text（由于众所周知的＆＃34; sublime＆＃34;隐藏字符的问题，但不会改变任何东西）改为Brackets ...
