pandas Panel 的使用

1、可以使用多种方式创建Panel，3D ndarrayimport pandas as pdimport numpy as npdata = np.random.rand(2,4,5)p = pd.Panel(data)print p

7、形状返回表示DataFrame维度的元组。元组（a，b），其中a表示行墙绅褡孛数，b表示列数。import pandas as pdd = {'Name': pd.Series(['zhangsan', 'xiaomin', 'lisi', 'lili']), 'Phone': pd.Series([13537106722, 13537106721, 13537106726, 13737106726]), 'Age': pd.Series([22, 24, 25 , 26])}# Create a DataFramedf = pd.DataFrame(d)print ("object:")print dfprint ("shape:")print df.shape输出：object: Age Name Phone0 22 zhangsan 135371067221 24 xiaomin 135371067212 25 lisi 135371067263 26 lili 13737106726shape:(4, 3)
