什么是质数？ (What is a prime number?)

A prime number is a natural number that is greater than 1 and cannot be formed by multiplying two smaller natural numbers.

质数是大于1的自然数，不能通过将两个较小的自然数相乘而形成。

Given a number num, we have to check whether num is a prime number or not.

给定数字num ，我们必须检查num是否是质数。

Example:

例：

Input:

num = 59

Output:

59 is a prime number

Input:

num = 123

Output:

123 is not a prime number

程序检查Python中的素数 (Program to check prime number in Python)

# Python program to check prime number

# Function to check prime number

def isPrime(n):

return all([(n % j) for j in range(2, int(n/2)+1)]) and n>1

# Main code

num = 59

if isPrime(num):

print(num, "is a prime number")

else:

print(num, "is not a prime number")

num = 7

if isPrime(num):

print(num, "is a prime number")

else:

print(num, "is not a prime number")

num = 123

if isPrime(num):

print(num, "is a prime number")

else:

print(num, "is not a prime number")

Output

输出量

59 is a prime number

7 is a prime number

123 is not a prime number
