How to find prime numbers using python

How to use python to find prime numbers within 100?

Prime numbers are also called prime numbers, and there are infinite numbers. A prime number is defined as a number that has no other factors except 1 and itself among natural numbers greater than 1, such as: 2, 3, 5, 7, 11, 13, 17, 19.

Method 1, use for loop to implement

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)
Copy after login

Method 2, use function to implement

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)
Copy after login

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]
