Python Pandas - 更改索引名称
要更改索引名称,请使用Pandas 中的方法。首先,导入所需的库 -index.rename()
import pandas as pd
创建熊猫索引 -
index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')
显示熊猫指数 -
print("Pandas Index...\n",index)
重命名索引 -
print("\nRename the index...\n",index.rename('Mode_of_Transport'))
示例
以下是代码 -
import pandas as pd输出结果# 创建 Pandas 索引
index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')
# 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)
# 重命名索引
print("\nRename the index...\n",index.rename('Mode_of_Transport'))
这将产生以下输出 -
Pandas Index...Index(['Car', 'Bike', 'Airplane', 'Ship', 'Truck', 'Suburban'], dtype='object', name='Transport')
Number of elements in the index...
6
The dtype object...
object
Rename the index...
Index(['Car', 'Bike', 'Airplane', 'Ship', 'Truck', 'Suburban'], dtype='object', name='Mode_of_Transport')
