Python|熊猫面板.shape

在 Pandas 中,Panel 是一个非常重要的 3D 数据容器。 3 个轴的名称旨在为描述涉及面板数据的操作提供一些语义含义,特别是面板数据的计量经济学分析。
在 Pandas中 Panel.shape可用于获取轴尺寸的元组。

Python3
# importing pandas module 
import pandas as pd 
import numpy as np
   
df1 = pd.DataFrame({'a': ['Geeks', 'For', 'geeks', 'for', 'real'], 
                    'b': [11, 1.025, 333, 114.48, 1333]})
                       
data = {'item1':df1, 'item2':df1}
   
# creating Panel 
panel = pd.Panel.from_dict(data, orient ='minor')
   
print("panel['b'] is - \n\n", panel['b'], '\n')
   
print("\nSize of panel['b'] is - ", panel['b'].shape)

# Create a 5 * 5 dataframe
df2 = pd.DataFrame(np.random.rand(10, 2), columns =['a', 'b'])

print("panel['b'] is - \n\n", panel['b'], '\n')
 
 
print("\nShape of Panel is - ", panel['b'].shape)


Python3
# importing pandas module

                    'b': [-11, +1.025, -114.48, 1333]})
 
df2 = pd.DataFrame({'a': ['I', 'am', 'dataframe', 'two'],
                    'b': [100, 100, 100, 100]})
                     
data = {'item1':df1, 'item2':df2}

输出:

注意:面板已从 Pandas 模块 0.25.0 开始删除。
