python判斷素數程序

什么是質數？ (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.

質數是大于1的自然數，不能通過將兩個較小的自然數相乘而形成。

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

給定數字num ，我們必須檢查num是否是質數。

Example:

例：

Input:num = 59Output:59 is a prime numberInput:num = 123Output:123 is not a prime number

程序檢查Python中的素數 (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

輸出量

59 is a prime number 7 is a prime number 123 is not a prime number
