Python Pandas Panel.rdiv()用法及代码示例


在 Pandas 中,Panel是一个非常重要的三维数据容器。 3个轴的名称旨在为描述涉及面板数据的操作,尤其是面板数据的计量分析提供一些语义上的含义。

在 Pandas Panel.rdiv()函数用于获取序列和 DataFrame /面板的划分。

用法: Panel.rdiv(other, axis=0)

参数:
other: DataFrame 或面板
axis:广播轴

返回:面板

代码1:

# importing pandas module  
import pandas as pd  
import numpy as np  
  
df1 = pd.DataFrame({'a':['Geeks', 'For', 'geeks', 'real'],  
                    'b':[111, 123, 425, 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("\nDividing panel['b'] with df2['b'] using rdiv() method - \n")  
print("\n", panel['b'].rdiv(df2['b'], axis = 0)) 
输出:
panel['b'] is - 

    item1  item2
0    111    100
1    123    100
2    425    100
3   1333    100

Dividing panel['b'] with df2['b'] using rdiv() method - 


       item1  item2
0  0.900901      1
1  0.813008      1
2  0.235294      1
3  0.075019      1

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]})  
  
data = {'item1':df1, 'item2':df1}  
  
# creating Panel  
panel = pd.Panel.from_dict(data, orient ='minor')  
print("panel['b'] is - \n\n", panel['b'], '\n')  
  
# Create a 5 * 5 dataframe  
df2 = pd.DataFrame(np.random.rand(5, 2), columns =['item1', 'item2'])  
print("Newly create dataframe with random values is - \n\n", df2) 
  
print("\nDividing panel['b'] with df2 using rdiv() method - \n")  
print(panel['b'].rdiv(df2, axis = 0)) 
输出:
panel['b'] is - 

       item1     item2
0    11.000    11.000
1     1.025     1.025

3   114.480   114.480
4  1333.000  1333.000 

Newly create dataframe with random values is - 

       item1     item2

3  0.429503  0.033674
4  0.151454  0.658271

Dividing panel['b'] with df2 using rdiv() method - 

      item1     item2
0  0.033160  0.061837
1  0.785288  0.837344
