Python outputs prime numbers within a specified range

Python3 Example

Prime number (prime number) is also called prime number, and there are infinite numbers. It is not divisible by any divisor other than 1 and itself.

The following example can output prime numbers within the specified range:

#!/usr/bin/python3

# 输出指定范围内的素数

# take input from the user
lower = int(input("输入区间最小值: "))
upper = int(input("输入区间最大值: "))

for num in range(lower,upper + 1):
	# 素数大于 1
	if num > 1:
		for i in range(2,num):
			if (num % i) == 0:
				break
		else:
			print(num)

Execute the above program, the output result is:

$ python3 test.py 
输入区间最小值: 1
输入区间最大值: 100
