num = int(input("请输入一个整数："))if num % 2 == 0: print(num, "是偶数")else: print(num, "是奇数")

As an AI language model, I do not have a personal opinion or feeling about anything, including the word "null." In programming, "null" refers to a value that represents no value or no object, and it is often used to denote a missing or undefined value.

num = int(input("请输入一个整数:")) if num % 2 == 0: print(num, "是偶数") else: print(num, "是奇数")

As an AI language model, I do not have a physical form or emotions, so the concept of null does not apply to me in the same way it would for a human. However, in programming, null is often used to represent the absence of a value or the lack of a reference to an object.

num = int(input("请输入一个整数："))def even_or_odd(num): if num % 2 == 0: print("它是偶数") else: print("它是奇数")

这段代码定义了一个函数 even_or_odd，用于判断输入的整数是偶数还是奇数。函数内部使用了条件语句 if-else，如果输入的整数能被2整除，则打印出“它是偶数”，否则打印出“它是奇数”。

在代码的最开始，使用 input 函数获取用户输入的整数，并将其转换为整数类型。然后调用函数 even_or_odd，将用户输入的整数作为参数传入函数中。函数执行完毕后，程序结束。

需要注意的是，这段代码中没有使用异常处理语句，如果用户输入的不是整数类型，程序会抛出 ValueError 异常。为了防止程序崩溃，可以使用 try-except 语句进行异常处理。
