Python Pandas - 创建一个既包含原始索引又包含名称的 Series


要创建一个同时包含原始索引和名称的 Series,请在 Pandas 中使用 index.to_series() 方法。首先,导入所需的库 -

import pandas as pd

创建 Pandas 索引

index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'],name ='Products')

将索引转换为 Series −

print("\nIndex to series...\n",index.to_series())

示例

以下是代码 −

import pandas as pd

# Creating Pandas index
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'],name ='Products')

# 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)

# convert index to series
print("\nIndex to series...\n",index.to_series())

输出

这将产生以下输出 −

Pandas Index...
Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], dtype='object', name='Products')

Number of elements in the index...
5

The dtype object...
object

Index to series...
Products
Electronics  Electronics
Accessories  Accessories
Decor              Decor
Books              Books
Toys                Toys
Name: Products, dtype: object
