python中checkpoint是什么python中check函数 三元运算符通常在Python里被称为条件表达式,这些表达式基于真(true)/假(not)的条件判断,在Python2.4以上才有了三元操作。 语法格式: X if C else Y 有了三元表达式,你只需一行就能完成条件判断和赋值操作: x, y = 3, 4 if x<y : smaller= x else smaller =y ...
# 定义函数check_number def check_number(number): if number % 2 == 0: print("偶数") else: print("奇数") # 调用函数check_number并传递参数 check_number(5) 上述示例中,函数check_number接受一个参数number,判断该参数是否为偶数,并输出相应的结果。通过调用函数check_number并传递参数5,可以...

So, if any number is divisible by any other number, it is not a prime number. Example 1: Program to Check Prime Number using a for loop public class Main { public static void main(String[] args) { int num = 29; boolean flag = false; // 0 and 1 are not prime numbers if (num...
