Python Pandas - 更改索引名称
若要更改索引名称,可在 Pandas 中使用 index.rename() 方法。首先,导入必需的库 -
import pandas as pd
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)重命名索引 -
print("\nRename the index...\n",index.rename('Mode_of_Transport'))
示例
以下为代码 -
import pandas as pd
# Creating Pandas index
index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')
# Display the Pandas index
print("Pandas Index...\n",index)
# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)
# Return the dtype of the data
print("\nThe dtype object...\n",index.dtype)
# Rename the index
print("\nRename the index...\n",index.rename('Mode_of_Transport'))输出
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')
