#题目：判断101-200之间有多少个素数，并输出所有素数。

from math import sqrt

l = []

for i in range(101,200):
    n = int(sqrt(i+1))
    leap = 1

    for x in range(2, n+1):
        if i % x == 0:
            leap = 0
    if leap == 1:
            l.append(i)


print(l,'Tatol is %d'%len(l))

# 参考答案

h = 0
leap = 1
from math import sqrt
from sys import stdout

    k = int(sqrt(m + 1))
    for i in range(2,k + 1):
