要重复索引的元素,请使用Pandas 中的方法。将重复次数设置为参数。首先,导入所需的库 -index.repeat()
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)
重复索引的元素 -
print("\nResult after repeating each index element twice...\n",index.repeat(2))
以下是代码 -
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) # 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) # 重复索引元素 print("\nResult after repeating each index element twice...\n",index.repeat(2))输出结果
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 Result after repeating each index element twice... Index(['Car', 'Car', 'Bike', 'Bike', 'Airplane', 'Airplane', 'Ship', 'Ship', 'Truck', 'Truck', 'Suburban', 'Suburban'], dtype='object', name='Transport')
