pandas的常用数据类型

1.Series 一维，带标签数组
2.Dataframe 二维，Series容器

pandas之Series创建

import  pandas as pd
t1=pd.Series([1,4,6,2,8,6],index=list("abcdef"))
print(t1)
print(t1.head(2))
print(t1.tail(2))
tem_dict={"name":"yiyi","age":"18"}
t2=pd.Series(tem_dict)

pandas之Series切片和索引

import  pandas as pd
t1=pd.Series([1,4,6,2,8,6],index=list("abcdef"))
print(t1)
print(t1.head(2))
print(t1.tail(2))
tem_dict={"name":"yiyi","age":"18"}
t2=pd.Series(tem_dict)

#series切片和索引
print(t2)
print(t2["name"])
print(t2["age"])
print(t2[0])
print(t2[1])
print(t1[t1>3])
