Python - 以不同的方式重複 Pandas 系列中的每個元素
要以不同的方式重複 Pandas 系列中的每個元素,請使用 index.repeat() 方法。首先,匯入所需的庫 -
import pandas as pd
建立 Pandas 索引 −
index = pd.Index(['Car','Bike','Airplane', 'Ship'], name ='Transport')
顯示 Pandas 索引 −
print("Pandas Index...\n",index)以不同的方式重複索引中的每個元素 −
print("\nResult after repeating each index element in a different way...\n", index.repeat([2,3,5,7]))示例
以下為程式碼 −
import pandas as pd
# Creating Pandas index
index = pd.Index(['Car','Bike','Airplane', 'Ship'], 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 each element of the index in a dissimilar way
print("\nResult after repeating each index element in a different way...\n", index.repeat([2,3,5,7]))輸出
這將產生以下輸出 −
Pandas Index... Index(['Car', 'Bike', 'Airplane', 'Ship'], dtype='object', name='Transport') Number of elements in the index... 4 The dtype object... object Result after repeating each index element in a different way... Index(['Car', 'Car', 'Bike', 'Bike', 'Bike', 'Airplane', 'Airplane', 'Airplane', 'Airplane', 'Airplane', 'Ship', 'Ship', 'Ship', 'Ship', 'Ship', 'Ship', 'Ship'], dtype='object', name='Transport')
