两道python的简单题目，本人非计算机专业

是期中考试，随便帮忙写出一道就行，就差一道了。
，可以的话发一下代码截图和运行结果截图

import numpy as np
salary = [10000, 8900, 9500, 30000, 24000, 26000]
salary_mean = np.mean(salary)
new_salary = []
for i in range(len(salary )):
      if salary[i] <salary_mean:
            new_salary.append(salary[i])
print(salary_mean)
print(new_salary)


salary = {"小明": 10000 ,\
          "小花": 9000  ,\
          "小红": 19000 ,\
          "小西": 16000 ,\
          "小东": 13000 ,\
          "小白": 12000  \
         }
salary_arg = sum(salary.values())/len(salary.keys())
print("平均工资：{:.2f}".format(salary_arg))   ### 保留小数点后两位
print("低于平均工资的有：")
for key in salary.keys():
    if(salary[key]<salary_arg):
        print("{}:{}".format(key,salary[key]))
