要返回由索引选择的值的新索引,请使用Pandas 中的方法。首先,导入所需的库——index.take()
import pandas as pd
创建熊猫索引 -
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')
显示熊猫指数 -
print("Pandas Index...\n",index)
获取由索引选择的值的新索引 -
print("\nA new Index of the values selected by the indices...\n",index.take([1,2]))
以下是代码 -
import pandas as pd # 创建 Pandas 索引 index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products') # 显示 Pandas 索引 print("Pandas Index...\n",index) # 返回索引中的元素数 print("\nNumber of elements in the index...\n",index.size) # 返回数据的 dtype print("\nThe dtype object...\n",index.dtype) # 获取索引选择的值的新索引 print("\nA new Index of the values selected by the indices...\n",index.take([1,2]))输出结果
这将产生以下输出 -
Pandas Index... Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], dtype='object', name='Products') Number of elements in the index... 5 The dtype object... object A new Index of the values selected by the indices... Index(['Accessories', 'Decor'], dtype='object', name='Products')
