Python Pandas:返回底层数据类型的 dtype 对象
若要返回底层数据的 dtype 对象,请在 Pandas 中使用 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 # Creating the index index = pd.Index(['Car','Bike', 'Shop','Car','Airplace', 'Truck']) # Display the index print("Pandas Index...\n",index) # Return an array representing the data in the Index print("\nArray...\n",index.values) # Return the dtype of the data print("\nThe dtype object...\n",index.dtype) # Return a tuple of the shape of the underlying data print("\nA tuple of the shape of underlying data...\n",index.shape)
输出
这将生成以下代码-
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,)
