Question

我正在尝试制作一个确定数字是奇数还是偶数的程序。该程序是用Python制作的，需要用户输入。

一个接受数字并告诉用户它是奇数还是偶数的程序

def OddorEven():
    try:
        number = input("Enter a number: ")
        int(number)
        oddoreven == number % 2
        if oddoreven == 0:
            print("Your number is an even number")
        else:
            print("Your numbe is an odd number")
        except:
            print("You did not enter a number!")
            OddorEven()

OddorEven()

发生异常：NameError 未定义名称“ oddoreven” 文件“ C：\ Users \ istif \ OneDrive \ Desktop \ New folder \ Even.py”，第4行，在奇数==数字％2

Answer 1

如果将数字转换为int，则应存储在某个变量中。

number = int（数字）然后做 Oddoreven =数字％2 并使用=分配符号而不是比较==符号因为如果您不将其存储在另一个变量中，则不会将其转换为int，然后仅将其视为字符串，这就是为什么您遇到typeerror

Answer 2

代码-

def OddorEven():
    try:
        number = input("Enter a number: ")
        number = int(number) #you have to assign the conversion to the variable again.
        oddoreven = number % 2 #remember = and == are not same. == is for comparison
        if oddoreven == 0:
            print("Your number is an even number")
        else:
            print("Your number is an odd number")
    except:
        print("You did not enter a number!")
        OddorEven()

OddorEven()

两个错误-

您必须将转换分配给变量
=和==不同。 Quick google search would help you better in detail

我不断收到TypeError
