Python Pandas Panel.truediv()用法及代碼示例

在 Pandas 中，Panel是一個非常重要的三維數據容器。 3個軸的名稱旨在為描述涉及麵板數據的操作，尤其是麵板數據的計量分析提供一些語義上的含義。

在 Pandas Panel.truediv()函數用於獲取係列和 DataFrame /麵板的浮點數劃分。

用法： Panel.truediv(other, axis=0)

參數：
other: DataFrame 或麵板
axis:廣播軸

返回：麵板

代碼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("\nFloating Dividing panel['b'] with df2['b'] using truediv() method - \n")  
print("\n", panel['b'].truediv(df2['b'], axis = 0))

輸出：

panel['b'] is - 

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

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


    item1  item2
0   1.11      1
1   1.23      1
2   4.25      1
