Python|熊猫 Panel.floordiv()

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 Panel.floordiv()函数用于获取系列和数据框/面板的整数除法。

Syntax: Panel.floordiv(other, axis=0)

Parameters:
other : DataFrame or Panel
axis : Axis to broadcast over

Returns: Panel

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)) 

输出：

panel['b'] is - 

    item1  item2
0    111    100
1    123    100
