要指示除最后一次出现之外的重复索引值,请使用. 使用值为last的keep参数。index.duplicated()
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','Airplane','Ship','Airplane'])
显示索引 -
print("Pandas Index with duplicates...\n",index)
将重复的索引值指示为 True,但最后一次出现除外。将“keep”参数设置为“last” -
print("\nIndicating duplicate values except the last occurrence...\n", index.duplicated(keep='last'))
以下是代码 -
import pandas as pd # Creating the index with some duplicates index = pd.Index(['Car','Bike','Airplane','Ship','Airplane']) # Display the index print("Pandas Index with duplicates...\n",index) # Return the dtype of the data print("\nThe dtype object...\n",index.dtype) # get the dimensions of the data print("\nGet the dimensions...\n",index.ndim) # Indicate duplicate index values as True, except the last occurrence # Set the "keep" 参数为 "last" print("\nIndicating duplicate values except the last occurrence...\n", index.duplicated(keep='last'))输出结果
这将产生以下代码 -
Pandas Index with duplicates... Index(['Car', 'Bike', 'Airplane', 'Ship', 'Airplane'], dtype='object') The dtype object... object Get the dimensions... 1 Indicating duplicate values except the last occurrence... [False False True False False]
