Python|熊猫 Panel.rtruediv()
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.rtruediv()函数用于获取系列和数据框/面板的浮动划分。
Syntax: Panel.rtruediv(other, axis=0)
Parameters:
other : DataFrame or Panel
axis : Axis to broadcast over
Returns: Panel

# 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("\nFloating Dividing panel['b'] with df2['b'] using rtruediv() method - \n")
