Python Pandas - 删除重复值的返回索引

2026-06-03 1 花语

要返回删除了重复值的索引,请使用该方法。index.drop_duplicates()

首先,导入所需的库-

import pandas as pd

创建具有一些重复项的索引-

index = pd.Index([Car,Bike,Truck,Car,Airplane])

显示索引-

print("Pandas Index with duplicates...\n",index)

删除重复值的返回索引。默认情况下,它会删除第一次出现的重复值-

print("\nIndex with duplicate values removed...\n",index.drop_duplicates())

示例

以下是代码-

import pandas as pd #创建具有一些重复项的索引 index = pd.Index([Car,Bike,Truck,Car,Airplane]) #显示索引 print("Pandas Index with duplicates...\n",index) #返回数据的dtype print("\nThe dtype object...\n",index.dtype) #获取数据中的字节 print("\nGet the bytes...\n",index.nbytes) #获取数据的维度 print("\nGet the dimensions...\n",index.ndim) #删除重复值的返回索引 #默认情况下,它会删除第一次出现的重复值 print("\nIndex with duplicate values removed...\n",index.drop_duplicates())输出结果

这将产生以下代码-

Pandas Index with duplicates... Index([Car, Bike, Truck, Car, Airplane], dtype=object) The dtype object... object Get the bytes... 40 Get the dimensions... 1 Index with duplicate values removed... Index([Car, Bike, Truck, Airplane], dtype=object)
