調查此代碼的錯誤？

Question

考慮下面的代碼，當我運行while循環執行後，if語句似乎不存在，我無法實現錯誤的地方。

while True: 

    IN = input(" ====================================== \n CPU scheduler console application: \n ====================================== \n 1.FCFS \n 2.SJF \n 3.Periority algorithm \n 4.Round robin \n 5.Exit \n Enter the chosen algorithm to run: ") 

if IN == 1: 
    Processes = input(" Enter the processes times & arrival times separated by a comma: ") 
    BurstTimes = Processes[::2] 
    ArrivalTimes = Processes[1::2] 
    print BurstTimes, '\t\t', ArrivalTimes, 
else: 
    print 'Good Bye!' 

Answer 1

縮進if條款：

while True: 

    IN = raw_input(" ====================================== \n CPU scheduler console application: \n ====================================== \n 1.FCFS \n 2.SJF \n 3.Periority algorithm \n 4.Round robin \n 5.Exit \n Enter the chosen algorithm to run: ") 

    if IN == '1': #change this to a string 

     Processes = input(" Enter the processes times & arrival times separated by a comma: ") 
     BurstTimes = Processes[::2] 
     ArrivalTimes = Processes[1::2] 
     print BurstTimes, '\t\t', ArrivalTimes, 
    else: 
     print 'Good Bye!' 

這是一個更好的做法是使用raw_input和字符串，而不是input - 它評估你的輸入，可能會危害您的代碼。
