Python Pandas - 返回对索引进行排序的整数索引
要返回对索引进行排序的整数索引,请使用Pandas 中的方法。首先,导入所需的库 -index.argsort()
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)
返回对索引进行排序的整数索引 -
res = index.argsort()
示例
以下是代码 -
import pandas as pd输出结果# 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)
res = index.argsort()
# 返回对索引进行排序的整数索引
print("\nThe integer indices to sort the index...\n",res)
print("\nOrdered..\n",index[res])
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
The integer indices to sort the index...
[1 3 2 0 4]
Ordered..
Index(['Accessories', 'Books', 'Decor', 'Electronics', 'Toys'], dtype='object', name='Products')
