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.floordiv()函數用於獲取序列和數據幀/麵板的整數除法。
用法: Panel.floordiv(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("\nInteger Dividing panel['b'] with df2['b'] using floordiv() method - \n")
print("\n", panel['b'].floordiv(df2['b'], axis = 0))
輸出:
panel['b'] is -
item1 item2
0 111 100
1 123 100
