Python Pandas - 將所有重複的索引值標記為 True
若要將所有重複的索引值標記為 True,請使用 index.duplicated()。將 keep 引數的值設為 False。
首先,匯入所需的庫 −
import pandas as pd
建立一些重複索引 −
index = pd.Index(['Car','Bike','Airplane','Ship','Airplane'])
顯示索引 −
print("Pandas Index with duplicates...\n",index)將所有重複的索引值標記為 True。將 "keep" 引數設為 "False" −
print("\nIndicating all duplicate index values True...\n", index.duplicated(keep=False))舉例
程式碼如下 −
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 all duplicate index values as True
# Set the "keep" parameter as "False"
print("\nIndicating all duplicate index values True...\n", index.duplicated(keep=False))輸出
將生成以下程式碼 −
Pandas Index with duplicates... Index(['Car', 'Bike', 'Airplane', 'Ship', 'Airplane'], dtype='object') The dtype object... object Get the dimensions... 1 Indicating all duplicate index values True... [False False True False True]
