Python Pandas - 返回索引值列表

要返回索引值的列表，请使用Pandas中的方法。首先，导入所需的库——index.to_list()

import pandas as pd

创建熊猫索引-

index = pd.Index([50.4, 10.2, 70.5, 110.5, 90.8, 50.6])

显示熊猫指数-

print("Pandas Index...\n",index)

返回列表-

print("\nList of the index values...\n",index.to_list())

示例

以下是代码-

import pandas as pd #创建Pandas索引 index = pd.Index([50.4, 10.2, 70.5, 110.5, 90.8, 50.6]) #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) #返回一个列表 print("\nList of the index values...\n",index.to_list())输出结果

这将产生以下输出-

Pandas Index... Float64Index([50.4, 10.2, 70.5, 110.5, 90.8, 50.6], dtype=float64) Number of elements in the index... 6 The dtype object... float64 List of the index values... [50.4, 10.2, 70.5, 110.5, 90.8, 50.6]
