我需要在Python中创建一个程序,要求用户输入一个数字,然后告诉用户该数字是偶数还是可以被5整除。如果两者都不是,则不要打印任何内容。例如:
Please enter a number: 5
This number is divisible by 5!
Please enter a number: 7
Please enter a number: 20
This number is even!
This number is divisible by 5!
我尝试复制this answer中使用的方法,但我在第8行收到错误消息:
SyntaxError: invalid syntax (<string>, line 8) (if Num_1 % 2 == 0)
这是我的代码:
#TODO 1: Ask for user input
Num1 = input("Please enter a number")
#TODO 2: Turn input into integer
Num_1 = int(Num1)
#TODO 2: Use conditionals to tell the user whether or not their
#number is even and/or divisible by 5
if Num_1 % 2 == 0
print ("This number is even!")
if Num_1 % 5 == 0
print ("This number is divisible by 5!")
由于我使用模数运算符来确定Num_1是否是2的精确倍数,我应该返回一个值True,因此应该打印“这个数字是偶数!”但相反,我收到此错误消息 - 为什么?谢谢!
答案 0 :(得分:2)
每个Python块的开头应以冒号:
结束。另请注意缩进。
Num1 = input("Please enter a number")
Num_1 = int(Num1)
if Num_1 % 2 == 0:
print ("This number is even!")
if Num_1 % 5 == 0:
print ("This number is divisible by 5!")
