Python Pandas - 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。首先,导入所需的库-index.sort_values()
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。默认情况下,按升序排序-
print("\nSort the index values...\n",index.sort_values())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
#默认情况下,按升序排序
print("\nSort the index values...\n",index.sort_values())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... Int64Index([10, 30, 50, 70, 90, 95, 110], dtype='int64')
