investigate the error with this code?

Question

consider the following code when i run it only the line after while loop executed and the if statement seems like it doesnt exist i cannt realize where the error exactly.

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

Indent the if clause:

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!'

It's a better practice to use raw_input and strings instead of input - which evaluates your input and might be harmful to your code.
