代码如下

import math
def prime(n):
    if n==2:
        return True
    else:
        half = math.ceil(math.sqrt(n))
        count = 1
        for i in range(1,half+1):
            if n%i==0:
                count+=1
        if count==2 :
            return True
        else:
            return False

m,n = map(int,input().split(' '))
num = 0
prime_count = []

a=2
while num != n:
    if prime(a):
        num+=1
        prime_count.append(a)
    a+=1

prime_count = prime_count[m-1:]
count = 0
row = 0
for i in prime_count:

    if count!=9 and (row*10+count)!= len(prime_count)-1:
        print(i,end=' ')
        count+=1
    else:
        print(i)
        count=0
        row +=1
