Python - 以不同的方式重复 Pandas 系列中的每个元素
要以不同的方式重复 Pandas 系列中的每个元素,请使用 index.repeat() 方法。首先,导入所需的库 -
import pandas as pd
创建 Pandas 索引 −
index = pd.Index(['Car','Bike','Airplane', 'Ship'], name ='Transport')
显示 Pandas 索引 −
print("Pandas Index...\n",index)
以不同的方式重复索引中的每个元素 −
print("\nResult after repeating each index element in a different way...\n", index.repeat([2,3,5,7]))
示例
以下为代码 −
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]))
输出
这将产生以下输出 −
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')
