Python Pandas - 重复索引元素


要在 Pandas 中重复索引元素,请使用 index.repeat() 方法。将重复数作为参数设置。首先,导入所需的库 −

import pandas as pd

创建 Pandas 索引 −

index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')

显示 Pandas 索引 −

print("Pandas Index...\n",index)

重复索引元素 −

print("\nResult after repeating each index element twice...\n",index.repeat(2))

示例

以下是代码 −

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))

输出

这将产生以下输出 −

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')
