检查来自用户的输入是否为有效数字

Question

在下面的代码中，我试图检查输入的数字只是一个整数，并且不小于1。如果我首先输入负数作为验证的输入，然后输入正确的值，则它不返回值

输出1：

Enter the No of fruits:text
text is not an integer.
Enter the No of fruits:-1
Enter a valid number
Enter the No of fruits:5
Outside while
Outside while

输出2：

Enter the No of fruits:text
text is not an integer.
Enter the No of fruits:5
Outside while
Enter the fruit Type:

代码：

def getNoOfFruits():
    count = 0
    while count is 0:
        inputnum = input("Enter the No of fruits:")
        try:
            count =int(inputnum )
        except ValueError:
            print("%s is not an integer.\n" % inputnum )
            continue
        if count < 1:
            print("Enter a valid number")
            getNoOfFruits()
        else:
            break
    print("Outside while")
    return count

No_Of_Fruits = getNoOfFruits()
type = input("Enter the fruit Type:")
