Python Pandas - 重复索引的元素

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))

示例

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)
