Python | Pandas panel.floor div()

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

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。

熊猫中**Panel.floordiv()**函数用于获取数列和数据框/面板的整数除法。

语法: Panel.floordiv(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', '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("\nInteger Dividing panel['b'] with df2['b'] using floordiv() method - \n") 
print("\n", panel['b'].floordiv(df2['b'], axis = 0)) 

Output:

panel['b'] is - 

    item1  item2
0    111    100
1    123    100
2    425    100
