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]
