Python Pandas - 按降序返回索引的排序副本
要返回索引的排序副本,请使用Pandas中的方法。参数升序设置为False。index.sort_values()
首先,导入所需的库-
import pandas as pd
创建熊猫索引-
index = pd.Index([50, 10, 70, 95, 110, 90, 30])
显示熊猫指数-
print("Pandas Index...\n",index)
排序索引值。要按降序对值进行排序,请将“升序”参数设置为“假”-
print("\nSort the index values in descending order...\n",index.sort_values(ascending=False))
示例
以下是代码-
import pandas as pd #创建Pandas索引 index = pd.Index([50, 10, 70, 95, 110, 90, 30]) #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) #排序索引值 # To sort values in Descending order, set the "ascending" 参数到 "False" print("\nSort the index values in descending order...\n",index.sort_values(ascending=False))输出结果
这将产生以下输出-
Pandas Index... Int64Index([50, 10, 70, 95, 110, 90, 30], dtype='int64') Number of elements in the index... 7 The dtype object... int64 Sort the index values in descending order... Int64Index([110, 95, 90, 70, 50, 30, 10], dtype='int64')
