如何在Python

Question

我正在摆弄我从CSGO reddit收到的一些代码，使用刚刚发布的游戏状态集成实现炸弹计时器，我已设法使代码使用HTTP Post JSON，如下所示：

import time
import SimpleHTTPServer
import SocketServer
import logging
import cgi
import sys
import json
import signal

PORT = 3000
planted = False

#If we ctrl+C out of python, make sure we close the serial port first
#handler catches and closes it
def signal_handler(signal, frame):
    ser.close()
    sys.exit(0)

class ServerHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
    def do_GET(self):
        SimpleHTTPServer.SimpleHTTPRequestHandler.do_GET(self)


    #SimpleHTTPServer doesn't handle post by default. Hacked up way to do it here
    def do_POST(self):
        length = int(self.headers["Content-Length"])
        jsonString = str(self.rfile.read(length))
        print jsonString
        print "---"
        jsonDict = json.loads(jsonString)
        #From here we have a JSON dict, that has whatever data CS is sending

        #For the timer, all we care about is the the 'round' key 

        if 'round' in jsonDict:
            rounds = jsonDict['round']
            if 'bomb' in rounds:
                if rounds['bomb'] == "planted":
                    planted = True
                    print "Bomb has been planted"

                    #timer code here

                    def main():
                        x = 10
                        for i in range(x + 1):
                            time.sleep(1)
                            print(formatTime(x))
                            x -= 1
                    def formatTime(x):
                        minutes = int(x / 60)
                        seconds_rem = int(x % 60)
                        if (seconds_rem < 10):
                            return(str(minutes) + ":0" + str(seconds_rem))
                        else:
                            return(str(minutes) + ":" + str(seconds_rem))
                    main()


                #If bomb has been defused, then send the 'C' message
                if rounds['bomb'] == "defused":
                    planted = False
                    print "bomb has been defused"

                #if the round ends, either bomb exploded or everyone died. 
                #Send the 'C' message to stop timer.
                if 'previously' in jsonDict:
                    if 'round' in jsonDict['previously']:
                        if 'bomb' in jsonDict['previously']['round']:
                            planted = False
                            print "Round ran out"

        #not sure if a response is really required. Send it anyway
        response = bytes("This is the response.") #create response

        self.send_response(200) #create header
        self.send_header("Content-Length", str(len(response)))
        self.end_headers()
        self.wfile.write(response) #send response


Handler = ServerHandler
#On windows, Serial ports are usually COM1-3
#On mac/linux this will be different
#Set up our handler for ctrl+c
signal.signal(signal.SIGINT, signal_handler)

#Start server
httpd = SocketServer.TCPServer(("", PORT), Handler)


#Run server
httpd.serve_forever()

然而，这部分代码：

def main():
    x = 10
    for i in range(x + 1):
        time.sleep(1)
        print(formatTime(x))
        x -= 1
def formatTime(x):
    minutes = int(x / 60)
    seconds_rem = int(x % 60)
    if (seconds_rem < 10):
        return(str(minutes) + ":0" + str(seconds_rem))
    else:
        return(str(minutes) + ":" + str(seconds_rem))
main()

运行自己两次，如python shell日志中所示，并且它说炸弹已被种植，即使该回合已经完全结束，想知道是否有人知道它为什么会自行运行两次。
