python生成两组随机数并写入csv中，该怎么把这些数组生成列表然后让他变成表格啊

让这两个[ ]内的数变成两列数，变成一个表格，帮帮我吧 我吧谢谢大家好人一生平安

import csv
import random
    
temp = list(range(1, 501))
random.shuffle(temp)
r1 = [temp[i*100:(i+1)*100]  for i in range(len(temp) //100)]
print(r1)
random.shuffle(temp)
r2 = [temp[i*100:(i+1)*100]  for i in range(len(temp) //100)]
print(r2)

with open('x.csv',mode ='w+', newline = '', encoding = 'utf-8') as f:
    c = csv.writer(f)
    c.writerows(r1)
    c.writerows(r2)
