Python Pandas Panel.shape

在Pandas中，面板是一个非常重要的三维数据的容器。3个轴的名称是为了给描述涉及面板数据的操作，特别是面板数据的计量经济学分析，提供一些语义上的意义。
在Pandas中，Panel.shape可以用来获得一个轴尺寸的元组。

语法: Panel.shape
参数: None
返回： 返回一个轴尺寸的元组

代码 #1:

# 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)  

输出:

代码 #2:

# 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]})
 
# Create a 5 * 5 dataframe
df2 = pd.DataFrame(np.random.rand(10, 2), columns =['a', 'b'])
   
data = {'item1':df1, 'item2':df2}
   
# creating Panel 
panel = pd.Panel.from_dict(data, orient ='minor')
print("panel['b'] is - \n\n", panel['b'], '\n')
 
 
print("\nShape of Panel is - ", panel['b'].shape)

输出:

代码 #3:

# importing pandas module
import pandas as pd
import numpy as np
 
df1 = pd.DataFrame({'a': ['Geeks', 'For', 'geeks', 'real'],
                    '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}
 
# creating Panel
panel = pd.Panel.from_dict(data, orient ='minor')
print("panel['b'] is - \n\n", panel['b'])
 
print("\nShape of panel['b'] is - ",  panel['b'].shape)

输出:

注意：该面板已从Pandas模块0.25.0起被移除。
