要以不同的方式重复 Pandas 系列的每个元素,请使用该方法。首先,导入所需的库——index.repeat()
import pandas as pd
创建熊猫索引 -
index = pd.Index(['Car','Bike','Airplane', 'Ship'], name ='Transport')
显示熊猫指数 -
print("Pandas Index...\n",index)
以不同的方式重复索引的每个元素 -
print("\nResult after repeating each index element in a different way...\n", index.repeat([2,3,5,7]))
以下是代码 -
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) # 返回索引中的元素数 print("\nNumber of elements in the index...\n",index.size) # 返回数据的 dtype print("\nThe dtype object...\n",index.dtype) # 以不同的方式重复索引的每个元素 print("\nResult after repeating each index element in a different way...\n", index.repeat([2,3,5,7]))
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')
