Python Pandas - 检查索引是否有重复值
要检查索引是否有重复值，请使用Pandas中的index.has_duplicates属性。
首先，导入所需的库-
import pandas as pd
创建索引-
index = pd.Index(['Car','Bike','Truck','Car','Airplane'])
显示索引-
print("Pandas Index...\n",index)检查索引是否具有重复值-
print("\nIs the Pandas index having duplicate values?\n",index.has_duplicates)示例
以下是代码-
import pandas as pd
#创建索引
index = pd.Index(['Car','Bike','Truck','Car','Airplane'])
#显示索引
print("Pandas Index...\n",index)
#返回一个表示索引中数据的数组
print("\nArray...\n",index.values)
#检查索引是否有重复值
print("\nIs the Pandas index having duplicate values?\n",index.has_duplicates)输出结果这将产生以下代码-
Pandas Index... Index(['Car', 'Bike', 'Truck', 'Car', 'Airplane'], dtype='object') Array... ['Car' 'Bike' 'Truck' 'Car' 'Airplane'] Is the Pandas index having duplicate values? True
