[TOC] ***** ## 1.2. DataFrame 與 Series dataframe是二維結構化數據，series是一維數據。 dataframe有一個或者多個series組成，dataframe的一行或者一列就是一個series。 ### 1.2.1. Series的創建 **Series是能夠存儲任意數據類型的一維標簽數組** ``` # 根據字典創建series a = {"name":"xiaoming","age":18,"sex":"male"} pd.Series(a,name='dict') ```  ``` # From scala pd.Series(5,index=list("abcdef")) ```  ``` #根據列表創建series s1 b = [1,2,3,4,5,6] s1 = pd.Series(b,index = list("abcdef")) ``` series的values屬性和index屬性   ### 1.2.2. DataFrame的創建 DataFrame中的任意一行或一列用type()都可知類型是series ``` #根據字典創建series a = {"name":["xiaoming","xiaohong","xiaogang"],"age":[12,13,14]} pd.DataFrame(data = a,index = list('abc')) ```  ``` b = [ [1,2,3,4], ['a','b','c','d'] ] #根據二維數組創建series,abcd是列名，ab是索引 pd.DataFrame(b,columns=list("ABCD"),index= list('ab')) ```  ``` a = {"name":"xiaoming","age":18,"sex":"male"} s1 = pd.Series(a) df_ = pd.DataFrame(s1,columns = ['Values']) df_ ```
