（1）series
1.最简单的series例子
import pandas as pd
obj2 = pd.Series([1,2,3,4],index=['a','b','c','d'])
print(obj2)
2.通过字典创建series
import pandas as pd
dic = {"name":"mark","age":16,"grade":[55,69,78]}
s3 = pd.Series(dic)
print(s3)

d = [
[95,99,89,60],
[77,56,68,58],
[92,88,29,98],
[22,54,73,62]
]
data = pd.DataFrame(d,columns = ['shuxue','yuwen','yingyu','shengwu'],index =
[['banji1','banji2','banji3','banji4']])
