Python Pandas - 重複索引元素
要在 Pandas 中重複索引元素,請使用 index.repeat() 方法。將重複數作為引數設定。首先,匯入所需的庫 −
import pandas as pd
建立 Pandas 索引 −
index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')
顯示 Pandas 索引 −
print("Pandas Index...\n",index)重複索引元素 −
print("\nResult after repeating each index element twice...\n",index.repeat(2))
示例
以下是程式碼 −
import pandas as pd
# Creating Pandas index
index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')
# Display the Pandas index
print("Pandas Index...\n",index)
# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)
# Return the dtype of the data
print("\nThe dtype object...\n",index.dtype)
# repeat elements of the index
print("\nResult after repeating each index element twice...\n",index.repeat(2))輸出
這將產生以下輸出 −
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')
