Python - Get prime numbers within 100
Python 100 ExamplesTitle: Get prime numbers within 100.
Program analysis:A prime number, also known as a prime, has infinitely many. A prime number is defined as a natural number greater than 1 that has no other factors besides 1 and itself, such as: 2, 3, 5, 7, 11, 13, 17, 19.
Method 1:
#!/usr/bin/python
# -*- coding: UTF-8 -*-
num=[];
i=2
for i in range(2,100):
j=2
for j in range(2,i):
if(i%j==0):
break
else:
num.append(i)
print(num)
Method 2:
import math
def func_get_prime(n):
return filter(lambda x: not [x%i for i in range(2, int(math.sqrt(x))+1) if x%i ==0], range(2,n+1))
print func_get_prime(100)
The output result is:
[2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]Other extensions
