python异常

Python code

while True :    try:        x = raw_input("Enter the first number :  ")        y = raw_input("Enter the second number :  ")        value = x/y        print "x/y is ", value    except :        print "something wrong , please try again "    else :        break

结果如下：

Enter the first number : 10
Enter the second number : 2
something wrong , please try again
Enter the first number : 10
Enter the second number : 0
something wrong , please try again
Enter the first number : 10
Enter the second number : 5
something wrong , please try again
Enter the first number :

问题：输入第一个数为10，第二个数为2 。。还是得不到正确结果5.



[解决办法]
value = int(x)/int(y)

another way:

Python code

#!python# encoding: utf-8import syserrStream = sys.stderroutStream = sys.stdoutdef getInt():    while True:        try:            n = int(raw_input('Enter an integer number:'))        except:            errStream.write('integer input error, try again\n')            continue        return ndef main():    while True:        x = getInt()        y = getInt()        try:            outStream.write('%d / %d is %d\n'%(                x, y, x/y))        except:            errStream.write('some error in div, try again\n')        else:            breakif __name__ == '__main__':    main()
