Python Pandas - 返回底层数据的 dtype 对象

要返回底层数据的dtype对象，请使用Pandas中的index.dtype属性。

首先，导入所需的库-

import pandas as pd

创建索引-

index = pd.Index([Car,Bike, Shop,Car,Airplace, Truck])

显示索引-

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

返回数据的dtype-

print("\nThe dtype object...\n",index.dtype)

示例

以下是代码-

import pandas as pd #创建索引 index = pd.Index([Car,Bike, Shop,Car,Airplace, Truck]) #显示索引 print("Pandas Index...\n",index) #返回一个表示索引中数据的数组 print("\nArray...\n",index.values) #返回数据的dtype print("\nThe dtype object...\n",index.dtype) #返回基础数据形状的元组 print("\nA tuple of the shape of underlying data...\n",index.shape)输出结果

这将产生以下代码-

Pandas Index... Index([Car, Bike, Shop, Car, Airplace, Truck], dtype=object) Array... [Car Bike Shop Car Airplace Truck] The dtype object... object A tuple of the shape of underlying data... (6,)
