Python|熊猫面板. radd()

原文:https://www.geeksforgeeks.org/python-pandas-panel-radd/

在熊猫中，面板是一个非常重要的三维数据容器。三个轴的名称旨在为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含义。

在熊猫中**Panel.radd()**功能用于序列和序列/数据帧的元素相加。相当于其他+面板。

语法: Panel.radd(其他，轴=0)

参数: 其他:数据框或面板 轴:轴广播结束

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', '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("\nAdding panel['b'] with df1['b'] using radd() method - \n")   
print("\n", panel['b'].radd(df1['b'], axis = 0)) 

Output:

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 

Adding panel['b'] with df1['b'] using radd() method -
